Makefile.in (c-decl.o): Depend on rtl.h and expr.h.
* Makefile.in (c-decl.o): Depend on rtl.h and expr.h.
* alias.c (struct alias_entry): alias_set is HOST_WIDE_INT.
(REG_BASE_VALUE): Remove unneeded cast to unsigned.
(get_alias_set_entry): ALIAS_SET arg is HOST_WIDE_INT.
(find_base_decl): New function, from c_find_base_decl in c-common.c.
(new_alias_set): Moved from tree.c; return is HOST_WIDE_INT.
(get_alias_set): Likewise.
Major rework to do more things and allow language-specific code
to just handle special-cases.
(record_alias_subset): Args are HOST_WIDE_INT.
(record_component_alias): Local vars are HOST_WIDE_INT.
Don't handle COMPLEX_EXPR.
(get_varargs_alias_set): Moved from builtins.c.
(get_frame_alias_set): New function.
* builtins.c (expand_builtin_return_address): Use frame alias set.
(expand_builtin_setjmp, expand_builtin_longjmp): Use alias set
for setjmp buffer.
(get_memory_rtx): Rework to use set_mem_attributes.
(get_varargs_alias_set): Deleted from here.
* c-common.c (c_apply_type_quals_to_decl): Alias sets now HOST_WIDE_INT.
(c_find_base_decl): Deleted from here.
(c_get_alias_set): Remove many cases and rework to just handle
C-specific cases.
* c-common.h (c_get_alias_set): Returns HOST_WIDE_INT.
* c-decl.c (rtl.h, expr.h): Now included.
(init_decl_processing): Call record_component_aliases on array types.
(grokdeclarator): Likewise.
Set TREE_ADDRESSABLE for all fields that are not bitfields.
* c-typeck.c (common_type): Call record_component_aliases for array.
* caller-save.c (setup_save_areas): Rework register loop for unsigned.
Set all save areas to the frame alias set.
* calls.c (initialie_argument_information): Call set_mem_attributes.
(compute_argument_addresses, expand_call): Likewise.
* explow.c (set_mem_attributes): New function.
(stabilize): Use MEM_COPY_ATTRIBUTES and force_reg.
* expr.c (struct move_by_pieces): Remove {to,from}_{struct,readonly}.
LEN and OFFSET now HOST_WIDE_INT.
(clear_by_pieces): Similar changes.

(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not

(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.

* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)

if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.

The ->type field stores the type of the declaration in this scope;

if NULL, the type is the type of the ->decl field. This is only of

|
|
relevance for objects with external or internal linkage which may

|
|

be redeclared in inner scopes, forming composite types that only

persist for the duration of those scopes. In the external scope,

this stores the composite of all the types declared for this

object, visible or not. The ->inner_comp field (used only at file

The depth field is copied from the scope structure that holds this

decl. It is used to preserve the proper ordering of the ->shadowed

field (see bind()) and also for a handful of special-case checks.

Finally, the invisible bit is true for a decl which should be

true for a decl that's been bound a second time in an inner scope;

All normal label declarations are recorded in the innermost
|
|
|
|
|
function scope, as are bindings of undeclared identifiers to
|
|
|
|
|
error_mark_node. (GCC permits nested functions as an extension,
|
|
|
|
|
hence the 'innermost' qualifier.) Explicitly declared labels

(using the __label__ extension) appear in the current scope.

Initially only the built-in declarations, which describe compiler
|
|
|
|
|
intrinsic functions plus a subset of the standard library, are in
|
|
|
|
|
this scope.
|
|
|
|
|
|
|
|
|
|
The order of the blocks list matters, and it is frequently appended
|
|
|
|
|
to. To avoid having to walk all the way to the end of the list on
|
|
|
|
|
each insertion, or reverse the list later, we maintain a pointer to
|
|
|
|
|
the last list entry. (FIXME: It should be feasible to use a reversed
|
|
|
|
|
list here.)
|
|
|
|
|
|
|
|
|
|
The bindings list is strictly in reverse order of declarations;
|
|
|
|
|
pop_scope relies on this. */

if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.

* c-decl.c (named_labels, shadowed_labels, label_level_chain)
(push_label_level, pop_label_level): Kill.
(struct binding_level): Rename level_chain to outer.
Add outer_function field. Change parm_flag, function_body,
keep, keep_if_subblocks to 1-bit bitfields of type bool.
(current_function_level): New variable.
(keep_next_level_flag, keep_next_if_subblocks): Change type to bool.
(keep_next_level, declare_parm_level, warn_if_shadowing):
Update to match.
(struct language_function): Kill named_labels, shadowed_labels fields.
(c_init_decl_processing, start_function, c_push__function_context)
(c_pop_function_context): No need to muck with named_labels nor
shadowed_labels.
(make_binding_level): No need to clear the structure here.
(pop_binding_level): Always operate on current_binding_level.
Update current_function_level if necessary.
(pushlevel): Don't clear named_labels. Update current_function_level
if necessary. Use "true" and "false" where appropriate.
(poplevel): Diagnose labels defined but not used, or vice
versa, and clear out label-meanings leaving scope, while
walking down the decls list, for all binding levels.
Handle LABEL_DECLs appearing in the shadowed list.
pop_binding_level takes no arguments.
(pushdecl_function_level): Use current_function_level.
(make_label, bind_label): New static functions.
(declare_label): New exported function.
(lookup_label, define_label): Rewritten for new data structure.
(shadow_label): Kill.
* c-tree.h: Prototype declare_label; don't prototype
push_label_level, pop_label_level, nor shadow_label.
* c-parse.in: Remove all calls to push_label_level and
pop_label_level. Use declare_label for __label__ decls.
* doc/extend.texi: Clarify that __label__ can be used to
declare labels with local scope in any nested block, not
just statement expressions. Cross-reference nested functions
section from local labels section.
testsuite:
* gcc.dg/noncompile/label-1.c: New comprehensive test case for
diagnostics of ill-formed constructs involving labels.
* gcc.dg/noncompile/label-lineno-1.c: Add error regexp for
the new 'previously defined here' message.

(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.

Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if

PR 12267, 12391, 12560, 13129, 14114, 14113
* c-tree.h: Forward declare struct c_binding. Declare
c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.
(truly_local_externals, first_builtin_decl, last_builtin_decl)

(mark_forward_parm_decls, build_compound_literal)
(grokdeclarator, start_function, check_for_loop_decls)
(identifier_global_value, record_builtin_type): Minor adjustments
for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.
* objc/objc-act.c: Adjust all calls to pushlevel, poplevel,
get_parm_info.
(OBJC_VOID_AT_END): Delete; replace all uses
with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:
* cp-lang.c (c_reset_state): Delete.
(push_file_scope, pop_file_scope): New stubs.
* parser.c (c_parse_file): Call sorry() here if called more than once.

re PR c/13801 (Decls should regain old type at end of scope)
PR c/13801
* c-decl.c (struct c_binding): Add type and inner_comp fields.
(bind): Set type and inner_comp fields.
(pop_scope): Restore type of decl to the correct type from an
outer scope. Give error when popping file scope for incomplete
arrays completed incompatibly with default initialization in an
inner scope.
(diagnose_mismatched_decls): Handle externs with initializers at
block scope.
(pushdecl): Set type of external declaration at block scope based
only on the visible declarations. Save type when changing the
type of a declaration. Merge an external declaration at block
scope with a visible static declaration at file scope.
(implicitly_declare): Give recycled old declaration the new type
except for incompatible declarations of built-in functions, saving
the old type.

(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.

scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for

initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.

expand_decl.

subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.

an older decl in the same binding level.

function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.

lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0

Use pushdecl_function_level.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.
* gcc.dg/Wshadow-1.c: Update error regexps.

Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around

(lookup_name): Adjust for new bindings structures. Kludge around

initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.

for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with

leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.

if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.
* gcc.dg/Wshadow-1.c: Update error regexps.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.
* gcc.dg/Wshadow-1.c: Update error regexps.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.
* gcc.dg/Wshadow-1.c: Update error regexps.

(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for

(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.

for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing

New static variables.

fields; remove parm_order.

(poplevel): Also clear bindings on the parms chain.
(pushdecl): Handle forward declarations of parameters, and
chain PARM_DECLs on the parms list, not the names list.

list too.
(push_parm_decl): Don't update parm_order.
(clear_parm_order): Rename mark_forward_parm_decls. Issue the
warning, only once per parameter list, and set TREE_ASM_WRITTEN
on the decls here. Then move the forward decls to the names list.
(grokparms): Set last_function_parm_vars.

extract non-parms from the parms list, or reorganize the parms
list. Feed nonparms back in the TREE_TYPE of the list node
returned. Issue only one error per parameter list for "void"
appearing more than once in said parameter list. Collapse
parmlist_tags_warning into this function to avoid double scan
of tags list.
(start_function): Set current_function_parm_vars.
(store_parm_decls_newstyle): Bypass pushdecl, manipulate scope
directly. Get non-parms from current_function_parm_vars; no
need to extract them from the parms chain. Properly bind tags
in the new scope.
(store_parm_decls_oldstyle): No need to extract non-parameters
from the parms chain, nor to store them back afterward. Move
declaration to top of function, restructure code reordering
DECL_ARGUMENTS.
(store_parm_decls): No need to save and restore warn_shadow.
* c-parse.in: Don't call parmlist_tags_warning nor
clear_parm_order. Call mark_forward_parm_decls when forward
parm decls are encountered.
* c-tree.h: Prototype mark_forward_parm_decls; not
clear_parm_order or parmlist_tags_warning.
testsuite:
* gcc.dg/struct-in-proto-1.c: New test.

* c-decl.c (struct c_binding): Add type and inner_comp fields.
(bind): Set type and inner_comp fields.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.
* gcc.dg/Wshadow-1.c: Update error regexps.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.

XFAIL builtin-noret-2.c at -O1 and above.

structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.

* c-tree.h: Forward declare struct c_binding. Declare
c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...

code duplication.

initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.

reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.

to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.

pushlevel/poplevel/declare_parm_level.

LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.

with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.

(scope_freelist): Move to more appropriate location.

(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.

(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous

Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl

Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for

initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>

local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.

(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.

IDENTIFIER_GLOBAL_VALUE.

PR 12267, 12391, 12560, 13129, 14114, 14113
* c-tree.h: Forward declare struct c_binding. Declare
c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.

* c-common.c (c_common_attribute_table): Allow
handle_visibility_attribute to be called for types.
(handle_visibility_attribute) When given a type, set the visibility
bits on the TYPE_NAME. When given a decl, don't set no_add_attrs
so that we can check later whether the attribute was present. Added
warning if attribute applied to non class type.
* c-decl.c (diagnose_mismatched_decls): Updated rules for merging
decls and checking that they are consistent.
* common.opt: Added -fvisibility.
* c.opt, c-opts.c: Added -fvisibility-inlines-hidden.
* c-pragma.h, c-pragma.c: Added handle_pragma_visibility().
* flags.h, tree.h: Added assorted support defines for overall patch
* opts.c: Added parsing support for -fvisibility.
* tree.c (build_decl): Set visibility for all decls to be whatever
is in force at that time.

(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.

Warn about YYDEBUG not being defined only if -dy. Remove no-longer-

if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge

* c-tree.h: Forward declare struct c_binding. Declare
c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.
(truly_local_externals, first_builtin_decl, last_builtin_decl)
(make_scope, pop_scope, in_parm_level_p, set_block)
(any_external_decl, record_external_decl, bind_label, getdecls)

(I_TAG_DECL, I_LABEL_BINDING, I_LABEL_DECL, file_scope)

(push_file_scope, pop_file_scope): New.

(mark_forward_parm_decls, build_compound_literal)
(grokdeclarator, start_function, check_for_loop_decls)
(identifier_global_value, record_builtin_type): Minor adjustments
for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.
* objc/objc-act.c: Adjust all calls to pushlevel, poplevel,
get_parm_info.
(OBJC_VOID_AT_END): Delete; replace all uses
with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:
* cp-lang.c (c_reset_state): Delete.
(push_file_scope, pop_file_scope): New stubs.
* parser.c (c_parse_file): Call sorry() here if called more than once.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,

(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,

(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,

(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.

Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.

global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.

IDENTIFIER_GLOBAL_VALUE.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>

local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.

(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.

* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:

structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.

(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.

for new data structures. Keep track of builtins that should be
made visible automatically.

expand_decl.

leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.

Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.

(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.

parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.

necessary. Always use plain warning.

(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.

global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.

IDENTIFIER_GLOBAL_VALUE.

/* Subroutine of pushdecl.
|
|
|
|
|
|
|
|
|
|
X is a TYPE_DECL for a typedef statement. Create a brand new
|
|
|
|
|
..._TYPE node (which will be just a variant of the existing
|
|
|
|
|
..._TYPE node with identical properties) and then install X
|
|
|
|
|
as the TYPE_NAME of this brand new (duplicate) ..._TYPE node.
|
|
|
|
|
|
|
|
|
|
The whole point here is to end up with a situation where each
|
|
|
|
|
and every ..._TYPE node the compiler creates will be uniquely
|
|
|
|
|
associated with AT MOST one node representing a typedef name.
|
|
|
|
|
This way, even though the compiler substitutes corresponding
|
|
|
|
|
..._TYPE nodes for TYPE_DECL (i.e. "typedef name") nodes very
|
|
|
|
|
early on, later parts of the compiler can always do the reverse
|
|
|
|
|
translation and get back the corresponding typedef name. For
|
|
|
|
|
example, given:
|
|
|
|
|
|
|
|
|
|
typedef struct S MY_TYPE;
|
|
|
|
|
MY_TYPE object;
|
|
|
|
|
|
|
|
|
|
Later parts of the compiler might only know that `object' was of
|
|
|
|
|
type `struct S' if it were not for code just below. With this
|
|
|
|
|
code however, later parts of the compiler see something like:
|
|
|
|
|
|
|
|
|
|
struct S' == struct S
|
|
|
|
|
typedef struct S' MY_TYPE;
|
|
|
|
|
struct S' object;
|
|
|
|
|
|
|
|
|
|
And they can then deduce (from the node for type struct S') that
|
|
|
|
|
the original object declaration was:
|
|
|
|
|
|
|
|
|
|
MY_TYPE object;
|
|
|
|
|
|
|
|
|
|
Being able to do this is important for proper support of protoize,
|
|
|
|
|
and also for generating precise symbolic debugging information
|
|
|
|
|
which takes full account of the programmer's (typedef) vocabulary.
|
|
|
|
|
|
|
|
|
|
Obviously, we don't want to generate a duplicate ..._TYPE node if
|
|
|
|
|
the TYPE_DECL node that we are now processing really represents a
|
|
|
|
|
standard built-in type.
|
|
|
|
|
|
|
|
|
|
Since all standard types are effectively declared at line zero
|
|
|
|
|
in the source file, we can easily check to see if we are working
|
|
|
|
|
on a standard type by checking the current value of lineno. */

(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,

(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.

function was defined with a prototype.

* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)

commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.

to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.

* gcc.c-torture/execute/builtin-noret-2.c: New.

list too.
(push_parm_decl): Don't update parm_order.

on the decls here. Then move the forward decls to the names list.

extract non-parms from the parms list, or reorganize the parms
list. Feed nonparms back in the TREE_TYPE of the list node
returned. Issue only one error per parameter list for "void"
appearing more than once in said parameter list. Collapse
parmlist_tags_warning into this function to avoid double scan
of tags list.
(start_function): Set current_function_parm_vars.
(store_parm_decls_newstyle): Bypass pushdecl, manipulate scope
directly. Get non-parms from current_function_parm_vars; no
need to extract them from the parms chain. Properly bind tags
in the new scope.
(store_parm_decls_oldstyle): No need to extract non-parameters
from the parms chain, nor to store them back afterward. Move
declaration to top of function, restructure code reordering
DECL_ARGUMENTS.
(store_parm_decls): No need to save and restore warn_shadow.
* c-parse.in: Don't call parmlist_tags_warning nor
clear_parm_order. Call mark_forward_parm_decls when forward
parm decls are encountered.
* c-tree.h: Prototype mark_forward_parm_decls; not
clear_parm_order or parmlist_tags_warning.

if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl

Warn about YYDEBUG not being defined only if -dy. Remove no-longer-

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.

(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.

only on the visible declarations. Save type when changing the
type of a declaration. Merge an external declaration at block
scope with a visible static declaration at file scope.

except for incompatible declarations of built-in functions, saving
the old type.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.
* gcc.dg/Wshadow-1.c: Update error regexps.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.

IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.

set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.

level on the transition from the parameters to the top level

necessary. Always use plain warning.

hit the FUNCTION_DECL.

PR 12267, 12391, 12560, 13129, 14114, 14113

c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.

for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.

get_parm_info.
(OBJC_VOID_AT_END): Delete; replace all uses
with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:

c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...

* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)

an empty TREE_LIST node. Adjust calls to get_parm_info.

to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.

(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.

scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.

function was defined with a prototype.

Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)

(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.

scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.

function was defined with a prototype.

IMA temporarily - an up-front error being preferable to a crash.)

to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.

if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.

* c-tree.h: Forward declare struct c_binding. Declare
c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.
(truly_local_externals, first_builtin_decl, last_builtin_decl)
(make_scope, pop_scope, in_parm_level_p, set_block)
(any_external_decl, record_external_decl, bind_label, getdecls)
(link_hash_hash, link_hash_eq, merge_translation_unit_decls)
(c_reset_state): Delete.

(c_binding, I_SYMBOL_BINDING, I_SYMBOL_DECL, I_TAG_BINDING)
(I_TAG_DECL, I_LABEL_BINDING, I_LABEL_DECL, file_scope)
(external_scope, binding_freelist, bind, free_binding_and_advance)
(push_file_scope, pop_file_scope): New.
(pushtag, pushdecl_top_level, lookup_label, declare_label)
(define_label, c_make_fname_decl, finish_decl)
(mark_forward_parm_decls, build_compound_literal)
(grokdeclarator, start_function, check_for_loop_decls)
(identifier_global_value, record_builtin_type): Minor adjustments
for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.
* objc/objc-act.c: Adjust all calls to pushlevel, poplevel,
get_parm_info.
(OBJC_VOID_AT_END): Delete; replace all uses
with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:
* cp-lang.c (c_reset_state): Delete.
(push_file_scope, pop_file_scope): New stubs.
* parser.c (c_parse_file): Call sorry() here if called more than once.

(pushlevel): Don't clear named_labels. Update current_function_level
if necessary. Use "true" and "false" where appropriate.
(poplevel): Diagnose labels defined but not used, or vice
versa, and clear out label-meanings leaving scope, while
walking down the decls list, for all binding levels.
Handle LABEL_DECLs appearing in the shadowed list.

pop_label_level. Use declare_label for __label__ decls.
* doc/extend.texi: Clarify that __label__ can be used to
declare labels with local scope in any nested block, not
just statement expressions. Cross-reference nested functions
section from local labels section.

2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.

(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.

call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.

set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.

local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.

global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.

IDENTIFIER_GLOBAL_VALUE.
cp:

scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.

(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.

for new data structures. Keep track of builtins that should be
made visible automatically.

expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.

reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.

Mark location where -pedantic changes the meaning of the program.

Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,

(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.

if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.
* gcc.dg/Wshadow-1.c: Update error regexps.

hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.

empty functions. Otherwise, don't call poplevel.

necessary. Always use plain warning.

instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.

global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.

IDENTIFIER_GLOBAL_VALUE.

PR 12267, 12391, 12560, 13129, 14114, 14113
* c-tree.h: Forward declare struct c_binding. Declare
c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.
(truly_local_externals, first_builtin_decl, last_builtin_decl)

(mark_forward_parm_decls, build_compound_literal)
(grokdeclarator, start_function, check_for_loop_decls)
(identifier_global_value, record_builtin_type): Minor adjustments
for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.
* objc/objc-act.c: Adjust all calls to pushlevel, poplevel,
get_parm_info.
(OBJC_VOID_AT_END): Delete; replace all uses
with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:
* cp-lang.c (c_reset_state): Delete.
(push_file_scope, pop_file_scope): New stubs.
* parser.c (c_parse_file): Call sorry() here if called more than once.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.

(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.

scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.

decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.
(truly_local_externals, first_builtin_decl, last_builtin_decl)

(mark_forward_parm_decls, build_compound_literal)

(identifier_global_value, record_builtin_type): Minor adjustments
for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.
* objc/objc-act.c: Adjust all calls to pushlevel, poplevel,
get_parm_info.
(OBJC_VOID_AT_END): Delete; replace all uses
with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:
* cp-lang.c (c_reset_state): Delete.
(push_file_scope, pop_file_scope): New stubs.
* parser.c (c_parse_file): Call sorry() here if called more than once.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.

First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.
(truly_local_externals, first_builtin_decl, last_builtin_decl)

(mark_forward_parm_decls, build_compound_literal)
(grokdeclarator, start_function, check_for_loop_decls)
(identifier_global_value, record_builtin_type): Minor adjustments
for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.
* objc/objc-act.c: Adjust all calls to pushlevel, poplevel,
get_parm_info.
(OBJC_VOID_AT_END): Delete; replace all uses
with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:
* cp-lang.c (c_reset_state): Delete.
(push_file_scope, pop_file_scope): New stubs.
* parser.c (c_parse_file): Call sorry() here if called more than once.

PR 12267, 12391, 12560, 13129, 14114, 14113
* c-tree.h: Forward declare struct c_binding. Declare
c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.
(truly_local_externals, first_builtin_decl, last_builtin_decl)
(make_scope, pop_scope, in_parm_level_p, set_block)
(any_external_decl, record_external_decl, bind_label, getdecls)

(I_TAG_DECL, I_LABEL_BINDING, I_LABEL_DECL, file_scope)

(mark_forward_parm_decls, build_compound_literal)
(grokdeclarator, start_function, check_for_loop_decls)
(identifier_global_value, record_builtin_type): Minor adjustments
for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.
* objc/objc-act.c: Adjust all calls to pushlevel, poplevel,
get_parm_info.
(OBJC_VOID_AT_END): Delete; replace all uses
with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:
* cp-lang.c (c_reset_state): Delete.
(push_file_scope, pop_file_scope): New stubs.
* parser.c (c_parse_file): Call sorry() here if called more than once.

c-common.c, [...]: Remove all references to obstack functions obsoleted by GC...
* c-common.c, c-decl.c, c-lang.c, c-lex.c, c-parse.in, c-pragma.c,
c-typeck.c, objc/objc-act.c: Remove all references to obstack
functions obsoleted by GC, such as push_obstacks_nochange,
end_temporary_allocation, savealloc, saveable_tree_cons, etc.
and code which existed only to decide whether or not to call
them. Remove now-unused NESTED argument from start_function;
all callers changed. Do not change behavior based on ggc_p.
The use of the ixp_obstack in c-iterate.c and the util_obstack
in objc/objc-act.c remain; these are not obsoleted by garbage
collection.
* c-tree.h: Update prototype for start_function.
* c-parse.y, c-parse.c, objc/objc-parse.c, objc/objc-parse.y: Rebuild.

* c-tree.h: Forward declare struct c_binding. Declare
c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.

for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.

get_parm_info.

with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:
* cp-lang.c (c_reset_state): Delete.
(push_file_scope, pop_file_scope): New stubs.

(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl

from the parms chain, nor to store them back afterward. Move
declaration to top of function, restructure code reordering
DECL_ARGUMENTS.
(store_parm_decls): No need to save and restore warn_shadow.
* c-parse.in: Don't call parmlist_tags_warning nor
clear_parm_order. Call mark_forward_parm_decls when forward
parm decls are encountered.

DECLSPECS is a c_declspecs structure for the declaration specifiers.
|
1992-02-13 23:21:26 +01:00
|
|
|
|
|
|
|
|
|
DECL_CONTEXT says which syntactic context this declaration is in:
|
|
|
|
|
NORMAL for most contexts. Make a VAR_DECL or FUNCTION_DECL or TYPE_DECL.
|
|
|
|
|
FUNCDEF for a function definition. Like NORMAL but a few different
|
|
|
|
|
error messages in each case. Return value may be zero meaning
|
|
|
|
|
this definition is too screwy to try to parse.
|
|
|
|
|
PARM for a parameter declaration (either within a function prototype
|
|
|
|
|
or before a function body). Make a PARM_DECL, or return void_type_node.
|
|
|
|
|
TYPENAME if for a typename (in a cast or sizeof).
|
|
|
|
|
Don't make a DECL node; just return the ..._TYPE node.
|
|
|
|
|
FIELD for a struct or union field; make a FIELD_DECL.
|
2004-08-22 00:47:32 +02:00
|
|
|
|
INITIALIZED is true if the decl has an initializer.
|
2003-12-17 01:25:24 +01:00
|
|
|
|
WIDTH is non-NULL for bit-fields, and is a pointer to an INTEGER_CST node
|
|
|
|
|
representing the width of the bit-field.
|
1992-02-13 23:21:26 +01:00
|
|
|
|
|
|
|
|
|
In the TYPENAME case, DECLARATOR is really an absolute declarator.
|
|
|
|
|
It may also be so in the PARM case, for a prototype where the
|
|
|
|
|
argument type is specified but not the name.
|
|
|
|
|
|
|
|
|
|
This function is where the complicated C meanings of `static'
|
1992-03-23 03:07:53 +01:00
|
|
|
|
and `extern' are interpreted. */

(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.

pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.

warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)

commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.

* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.

(pushdecl): Remove unnecessary assertion. Short-circuit anonymous

Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.

Warn about YYDEBUG not being defined only if -dy. Remove no-longer-

IMA temporarily - an up-front error being preferable to a crash.)

/* Decode the parameter-list info for a function type or function definition.

The argument is the value returned by `get_parm_info' (or made in parse.y
|
|
|
|
|
if there is an identifier list instead of a parameter decl list).
|
|
|
|
|
These two functions are separate because when a function returns
|
|
|
|
|
or receives functions then each is called multiple times but the order
|
|
|
|
|
of calls is different. The last call to `grokparms' is always the one
|
|
|
|
|
that contains the formal parameter names of a function definition.
|
|
|
|
|
|
|
|
|
|
Return a list of arg types to use in the FUNCTION_TYPE for this function.

FUNCDEF_FLAG is true for a function definition, false for
|
1992-02-13 23:21:26 +01:00

a mere declaration. A nonempty identifier-list gets an error message
|

when FUNCDEF_FLAG is false. */

if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge

returned. Issue only one error per parameter list for "void"

parmlist_tags_warning into this function to avoid double scan

from the parms chain, nor to store them back afterward. Move
declaration to top of function, restructure code reordering
DECL_ARGUMENTS.
(store_parm_decls): No need to save and restore warn_shadow.
* c-parse.in: Don't call parmlist_tags_warning nor
clear_parm_order. Call mark_forward_parm_decls when forward

* c-tree.h: Prototype mark_forward_parm_decls; not

c-decl.c (last_function_parm_vars, [...]): New static variables.
* c-decl.c (last_function_parm_vars, current_function_parm_vars):
New static variables.
(struct c_scope): Add parms and warned_forward_parm_decls
fields; remove parm_order.
(storedecls, storetags): Delete.
(poplevel): Also clear bindings on the parms chain.
(pushdecl): Handle forward declarations of parameters, and
chain PARM_DECLs on the parms list, not the names list.
(lookup_name_current_level): Check for PARM_DECLs on the parms
list too.
(push_parm_decl): Don't update parm_order.
(clear_parm_order): Rename mark_forward_parm_decls. Issue the
warning, only once per parameter list, and set TREE_ASM_WRITTEN
on the decls here. Then move the forward decls to the names list.
(grokparms): Set last_function_parm_vars.
(get_parm_info): Don't use gettags or getdecls. No need to
extract non-parms from the parms list, or reorganize the parms
list. Feed nonparms back in the TREE_TYPE of the list node
returned. Issue only one error per parameter list for "void"
appearing more than once in said parameter list. Collapse
parmlist_tags_warning into this function to avoid double scan
of tags list.
(start_function): Set current_function_parm_vars.
(store_parm_decls_newstyle): Bypass pushdecl, manipulate scope
directly. Get non-parms from current_function_parm_vars; no
need to extract them from the parms chain. Properly bind tags
in the new scope.
(store_parm_decls_oldstyle): No need to extract non-parameters
from the parms chain, nor to store them back afterward. Move
declaration to top of function, restructure code reordering
DECL_ARGUMENTS.
(store_parm_decls): No need to save and restore warn_shadow.
* c-parse.in: Don't call parmlist_tags_warning nor
clear_parm_order. Call mark_forward_parm_decls when forward
parm decls are encountered.
* c-tree.h: Prototype mark_forward_parm_decls; not
clear_parm_order or parmlist_tags_warning.
testsuite:
* gcc.dg/struct-in-proto-1.c: New test.

c-decl.c (last_function_parm_vars, [...]): New static variables.
* c-decl.c (last_function_parm_vars, current_function_parm_vars):
New static variables.
(struct c_scope): Add parms and warned_forward_parm_decls
fields; remove parm_order.
(storedecls, storetags): Delete.
(poplevel): Also clear bindings on the parms chain.
(pushdecl): Handle forward declarations of parameters, and
chain PARM_DECLs on the parms list, not the names list.
(lookup_name_current_level): Check for PARM_DECLs on the parms
list too.
(push_parm_decl): Don't update parm_order.
(clear_parm_order): Rename mark_forward_parm_decls. Issue the
warning, only once per parameter list, and set TREE_ASM_WRITTEN
on the decls here. Then move the forward decls to the names list.
(grokparms): Set last_function_parm_vars.
(get_parm_info): Don't use gettags or getdecls. No need to
extract non-parms from the parms list, or reorganize the parms
list. Feed nonparms back in the TREE_TYPE of the list node
returned. Issue only one error per parameter list for "void"
appearing more than once in said parameter list. Collapse
parmlist_tags_warning into this function to avoid double scan
of tags list.
(start_function): Set current_function_parm_vars.
(store_parm_decls_newstyle): Bypass pushdecl, manipulate scope
directly. Get non-parms from current_function_parm_vars; no
need to extract them from the parms chain. Properly bind tags
in the new scope.
(store_parm_decls_oldstyle): No need to extract non-parameters
from the parms chain, nor to store them back afterward. Move
declaration to top of function, restructure code reordering
DECL_ARGUMENTS.
(store_parm_decls): No need to save and restore warn_shadow.
* c-parse.in: Don't call parmlist_tags_warning nor
clear_parm_order. Call mark_forward_parm_decls when forward
parm decls are encountered.
* c-tree.h: Prototype mark_forward_parm_decls; not
clear_parm_order or parmlist_tags_warning.
testsuite:
* gcc.dg/struct-in-proto-1.c: New test.

fields; remove parm_order.

list too.
(push_parm_decl): Don't update parm_order.
(clear_parm_order): Rename mark_forward_parm_decls. Issue the
warning, only once per parameter list, and set TREE_ASM_WRITTEN
on the decls here. Then move the forward decls to the names list.
(grokparms): Set last_function_parm_vars.
(get_parm_info): Don't use gettags or getdecls. No need to
extract non-parms from the parms list, or reorganize the parms
list. Feed nonparms back in the TREE_TYPE of the list node
returned. Issue only one error per parameter list for "void"
appearing more than once in said parameter list. Collapse
parmlist_tags_warning into this function to avoid double scan
of tags list.
(start_function): Set current_function_parm_vars.
(store_parm_decls_newstyle): Bypass pushdecl, manipulate scope
directly. Get non-parms from current_function_parm_vars; no
need to extract them from the parms chain. Properly bind tags
in the new scope.
(store_parm_decls_oldstyle): No need to extract non-parameters
from the parms chain, nor to store them back afterward. Move
declaration to top of function, restructure code reordering
DECL_ARGUMENTS.
(store_parm_decls): No need to save and restore warn_shadow.
* c-parse.in: Don't call parmlist_tags_warning nor
clear_parm_order. Call mark_forward_parm_decls when forward
parm decls are encountered.
* c-tree.h: Prototype mark_forward_parm_decls; not
clear_parm_order or parmlist_tags_warning.
testsuite:
* gcc.dg/struct-in-proto-1.c: New test.

struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.

(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.

for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.

parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.

pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.

warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.

pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.

* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.

circular list rather than going into an infinite loop.
cp:

c-decl.c (last_function_parm_vars, [...]): New static variables.
* c-decl.c (last_function_parm_vars, current_function_parm_vars):
New static variables.
(struct c_scope): Add parms and warned_forward_parm_decls
fields; remove parm_order.
(storedecls, storetags): Delete.
(poplevel): Also clear bindings on the parms chain.
(pushdecl): Handle forward declarations of parameters, and
chain PARM_DECLs on the parms list, not the names list.
(lookup_name_current_level): Check for PARM_DECLs on the parms
list too.
(push_parm_decl): Don't update parm_order.
(clear_parm_order): Rename mark_forward_parm_decls. Issue the
warning, only once per parameter list, and set TREE_ASM_WRITTEN
on the decls here. Then move the forward decls to the names list.
(grokparms): Set last_function_parm_vars.
(get_parm_info): Don't use gettags or getdecls. No need to
extract non-parms from the parms list, or reorganize the parms
list. Feed nonparms back in the TREE_TYPE of the list node
returned. Issue only one error per parameter list for "void"
appearing more than once in said parameter list. Collapse
parmlist_tags_warning into this function to avoid double scan
of tags list.
(start_function): Set current_function_parm_vars.
(store_parm_decls_newstyle): Bypass pushdecl, manipulate scope
directly. Get non-parms from current_function_parm_vars; no
need to extract them from the parms chain. Properly bind tags
in the new scope.
(store_parm_decls_oldstyle): No need to extract non-parameters
from the parms chain, nor to store them back afterward. Move
declaration to top of function, restructure code reordering
DECL_ARGUMENTS.
(store_parm_decls): No need to save and restore warn_shadow.
* c-parse.in: Don't call parmlist_tags_warning nor
clear_parm_order. Call mark_forward_parm_decls when forward
parm decls are encountered.
* c-tree.h: Prototype mark_forward_parm_decls; not
clear_parm_order or parmlist_tags_warning.
testsuite:
* gcc.dg/struct-in-proto-1.c: New test.

c-decl.c (last_function_parm_vars, [...]): New static variables.
* c-decl.c (last_function_parm_vars, current_function_parm_vars):
New static variables.
(struct c_scope): Add parms and warned_forward_parm_decls
fields; remove parm_order.
(storedecls, storetags): Delete.
(poplevel): Also clear bindings on the parms chain.
(pushdecl): Handle forward declarations of parameters, and
chain PARM_DECLs on the parms list, not the names list.
(lookup_name_current_level): Check for PARM_DECLs on the parms
list too.
(push_parm_decl): Don't update parm_order.
(clear_parm_order): Rename mark_forward_parm_decls. Issue the
warning, only once per parameter list, and set TREE_ASM_WRITTEN
on the decls here. Then move the forward decls to the names list.
(grokparms): Set last_function_parm_vars.
(get_parm_info): Don't use gettags or getdecls. No need to
extract non-parms from the parms list, or reorganize the parms
list. Feed nonparms back in the TREE_TYPE of the list node
returned. Issue only one error per parameter list for "void"
appearing more than once in said parameter list. Collapse
parmlist_tags_warning into this function to avoid double scan
of tags list.
(start_function): Set current_function_parm_vars.
(store_parm_decls_newstyle): Bypass pushdecl, manipulate scope
directly. Get non-parms from current_function_parm_vars; no
need to extract them from the parms chain. Properly bind tags
in the new scope.
(store_parm_decls_oldstyle): No need to extract non-parameters
from the parms chain, nor to store them back afterward. Move
declaration to top of function, restructure code reordering
DECL_ARGUMENTS.
(store_parm_decls): No need to save and restore warn_shadow.
* c-parse.in: Don't call parmlist_tags_warning nor
clear_parm_order. Call mark_forward_parm_decls when forward
parm decls are encountered.
* c-tree.h: Prototype mark_forward_parm_decls; not
clear_parm_order or parmlist_tags_warning.

* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>

(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>

(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.

c-common.c, [...]: Remove all references to obstack functions obsoleted by GC...
* c-common.c, c-decl.c, c-lang.c, c-lex.c, c-parse.in, c-pragma.c,
c-typeck.c, objc/objc-act.c: Remove all references to obstack
functions obsoleted by GC, such as push_obstacks_nochange,
end_temporary_allocation, savealloc, saveable_tree_cons, etc.
and code which existed only to decide whether or not to call
them. Remove now-unused NESTED argument from start_function;
all callers changed. Do not change behavior based on ggc_p.
The use of the ixp_obstack in c-iterate.c and the util_obstack
in objc/objc-act.c remain; these are not obsoleted by garbage
collection.
* c-tree.h: Update prototype for start_function.
* c-parse.y, c-parse.c, objc/objc-parse.c, objc/objc-parse.y: Rebuild.

PR 12267, 12391, 12560, 13129, 14114, 14113
* c-tree.h: Forward declare struct c_binding. Declare
c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.
(truly_local_externals, first_builtin_decl, last_builtin_decl)
(make_scope, pop_scope, in_parm_level_p, set_block)
(any_external_decl, record_external_decl, bind_label, getdecls)

(I_TAG_DECL, I_LABEL_BINDING, I_LABEL_DECL, file_scope)
(external_scope, binding_freelist, bind, free_binding_and_advance)
(push_file_scope, pop_file_scope): New.
(pushtag, pushdecl_top_level, lookup_label, declare_label)
(define_label, c_make_fname_decl, finish_decl)
(mark_forward_parm_decls, build_compound_literal)
(grokdeclarator, start_function, check_for_loop_decls)
(identifier_global_value, record_builtin_type): Minor adjustments
for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.
* objc/objc-act.c: Adjust all calls to pushlevel, poplevel,
get_parm_info.
(OBJC_VOID_AT_END): Delete; replace all uses
with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:
* cp-lang.c (c_reset_state): Delete.
(push_file_scope, pop_file_scope): New stubs.
* parser.c (c_parse_file): Call sorry() here if called more than once.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.
* gcc.dg/Wshadow-1.c: Update error regexps.

locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.

Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.

initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.

for new data structures. Keep track of builtins that should be
made visible automatically.

expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.

* c-tree.h: Forward declare struct c_binding. Declare
c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.
(truly_local_externals, first_builtin_decl, last_builtin_decl)

for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.
* objc/objc-act.c: Adjust all calls to pushlevel, poplevel,
get_parm_info.
(OBJC_VOID_AT_END): Delete; replace all uses
with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:
* cp-lang.c (c_reset_state): Delete.
(push_file_scope, pop_file_scope): New stubs.
* parser.c (c_parse_file): Call sorry() here if called more than once.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.

* c-tree.h: Forward declare struct c_binding. Declare
c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.

for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.

* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.

(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.

* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,

(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:

struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.

(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.

Warn about YYDEBUG not being defined only if -dy. Remove no-longer-

(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.

pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.

(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.

(get_parm_info): Don't use gettags or getdecls. No need to
extract non-parms from the parms list, or reorganize the parms
list. Feed nonparms back in the TREE_TYPE of the list node
returned. Issue only one error per parameter list for "void"
appearing more than once in said parameter list. Collapse
parmlist_tags_warning into this function to avoid double scan
of tags list.
(start_function): Set current_function_parm_vars.
(store_parm_decls_newstyle): Bypass pushdecl, manipulate scope
directly. Get non-parms from current_function_parm_vars; no
need to extract them from the parms chain. Properly bind tags
in the new scope.
(store_parm_decls_oldstyle): No need to extract non-parameters
from the parms chain, nor to store them back afterward. Move
declaration to top of function, restructure code reordering
DECL_ARGUMENTS.
(store_parm_decls): No need to save and restore warn_shadow.
* c-parse.in: Don't call parmlist_tags_warning nor
clear_parm_order. Call mark_forward_parm_decls when forward
parm decls are encountered.
* c-tree.h: Prototype mark_forward_parm_decls; not
clear_parm_order or parmlist_tags_warning.

* gcc.dg/struct-in-proto-1.c: New test.

if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl

Warn about YYDEBUG not being defined only if -dy. Remove no-longer-

extract non-parms from the parms list, or reorganize the parms

need to extract them from the parms chain. Properly bind tags
in the new scope.
(store_parm_decls_oldstyle): No need to extract non-parameters
from the parms chain, nor to store them back afterward. Move
declaration to top of function, restructure code reordering
DECL_ARGUMENTS.
(store_parm_decls): No need to save and restore warn_shadow.
* c-parse.in: Don't call parmlist_tags_warning nor
clear_parm_order. Call mark_forward_parm_decls when forward
parm decls are encountered.

* c-decl.c (last_function_parm_vars, current_function_parm_vars):
New static variables.
(struct c_scope): Add parms and warned_forward_parm_decls
fields; remove parm_order.
(storedecls, storetags): Delete.
(poplevel): Also clear bindings on the parms chain.
(pushdecl): Handle forward declarations of parameters, and
chain PARM_DECLs on the parms list, not the names list.
(lookup_name_current_level): Check for PARM_DECLs on the parms
list too.
(push_parm_decl): Don't update parm_order.
(clear_parm_order): Rename mark_forward_parm_decls. Issue the
warning, only once per parameter list, and set TREE_ASM_WRITTEN
on the decls here. Then move the forward decls to the names list.
(grokparms): Set last_function_parm_vars.
(get_parm_info): Don't use gettags or getdecls. No need to
extract non-parms from the parms list, or reorganize the parms
list. Feed nonparms back in the TREE_TYPE of the list node
returned. Issue only one error per parameter list for "void"
appearing more than once in said parameter list. Collapse
parmlist_tags_warning into this function to avoid double scan
of tags list.
(start_function): Set current_function_parm_vars.
(store_parm_decls_newstyle): Bypass pushdecl, manipulate scope
directly. Get non-parms from current_function_parm_vars; no
need to extract them from the parms chain. Properly bind tags
in the new scope.
(store_parm_decls_oldstyle): No need to extract non-parameters
from the parms chain, nor to store them back afterward. Move
declaration to top of function, restructure code reordering
DECL_ARGUMENTS.
(store_parm_decls): No need to save and restore warn_shadow.
* c-parse.in: Don't call parmlist_tags_warning nor
clear_parm_order. Call mark_forward_parm_decls when forward
parm decls are encountered.
* c-tree.h: Prototype mark_forward_parm_decls; not
clear_parm_order or parmlist_tags_warning.

(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not

(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.

(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.

function was defined with a prototype.

(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.
(builtin_function): Use bind, not pushdecl. Adjust other bits
for new data structures. Keep track of builtins that should be
made visible automatically.
(start_decl): Adjust diagnostics. Remove unnecessary call to
expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.
(get_parm_info): Rename "void_at_end" argument to "ellipsis", with
reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.
(store_parm_decls): Correct the determination of whether a
function was defined with a prototype.
(c_write_global_declarations): Operate on all file decls and on
the external scope. Split body of the loop to...
(c_write_global_declarations_1): ... this new function, to avoid
code duplication.
(truly_local_externals, first_builtin_decl, last_builtin_decl)
(make_scope, pop_scope, in_parm_level_p, set_block)

(mark_forward_parm_decls, build_compound_literal)
(grokdeclarator, start_function, check_for_loop_decls)
(identifier_global_value, record_builtin_type): Minor adjustments
for new bindings structures. Improve diagnostics and commentary.
* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
pushlevel/poplevel respectively.
(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)
* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
(all actions): Adjust calls to pushlevel/poplevel.
(parsing_iso_function_signature): Delete.
(extdef_1): Fold into extdef.
(old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
warn here about function definitions in the wrong style.
(after_tyle_declarator, parm_declarator_starttypename)
(parm_declarator_nostarttypename, notype_declarator): Remove
commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.
* objc/objc-lang.c: Likewise.
* objc/objc-act.c: Adjust all calls to pushlevel, poplevel,
get_parm_info.
(OBJC_VOID_AT_END): Delete; replace all uses
with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.
* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
circular list rather than going into an infinite loop.
cp:
* cp-lang.c (c_reset_state): Delete.
(push_file_scope, pop_file_scope): New stubs.
* parser.c (c_parse_file): Call sorry() here if called more than once.

if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.
* gcc.dg/Wshadow-1.c: Update error regexps.

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.

reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.
(finish_struct, finish_enum): Remove redundant diagnostics.
(build_enumerator): Don't cascade diagnostics for error_mark_node.
Mark location where -pedantic changes the meaning of the program.
(store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
parameter decls into the function's scope structure using bind.
Warn here about function definitions in the wrong style.
Adjust diagnostics.

function was defined with a prototype.

the external scope. Split body of the loop to...

code duplication.

Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
correct loop over multiple translation units; call fatal_error if
requested to compile more than one file at once. (This disables
IMA temporarily - an up-front error being preferable to a crash.)

commented-out productions.
(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
an empty TREE_LIST node. Adjust calls to get_parm_info.
(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
to suppress -Wold-style-definition after this error.
(c_parse_file): Don't clear the binding stack or call
finish_fname_decls here. Correct comment.
* c-typeck.c (same_translation_unit_p): Export.
(common_type): Use c_override_global_bindings_to_false, not
pushlevel/poplevel/declare_parm_level.
* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
and LANG_HOOKS_GETDECLS with do-nothing stubs.

with void_list_node.
(generate_forward_declaration_to_string_table): Delete.
* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
* coverage.c (create_coverage): Don't pushdecl anything.
* langhooks.c (lhd_clear_binding_stack): Call
lang_hooks.decls.poplevel, not poplevel.

circular list rather than going into an infinite loop.
cp:

c-decl.c (struct binding_level): Add shadowed_tags and function_body...
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-decl.c (struct binding_level): Add shadowed_tags and
function_body; remove this_block, tag_transparent, and
subblocks_tag_transparent; update comments.
(clear_binding_level, lookup_tag_reverse): Kill.
(make_binding_level): Use ggc_alloc_cleared or memset.
(lookup_tag): Remove struct binding_level* parameter. All
callers changed. Just look at IDENTIFIER_TAG_VALUE, and
current_binding_level->tags if asked for thislevel_only or if
we might have to diagnose "struct foo; union foo;"
(pushlevel): Ignore argument. Do not push another binding
level on the transition from the parameters to the top level
of the function body; just tweak the flags and proceed.
(poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
a function body, separate the parameter list from the
top-level local variables.
(set_block): Do nothing.
(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
shadowed_tags if necessary.
(warn_if_shadowing): Nuke the special case for local shadowing
parameter.
(pushdecl): Do not create a shadow entry if we are replacing
an older decl in the same binding level.
(pushdecl_function_level): Tweak for new way of indicating
function scope.
(shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
(start_function): Don't set subblocks_tag_transparent.
(finish_function): Fix up the binding_level stack for totally
empty functions. Otherwise, don't call poplevel.
* c-common.c (shadow_warning): MANDATORY argument is no longer
necessary. Always use plain warning.
* c-common.h: Update to match.
* cfglayout.c (scope_to_insns_initialize): Clear block when we
hit the FUNCTION_DECL.
* function.c: Do not create cyclic tree structure.
2003-04-10 Zack Weinberg <zack@codesourcery.com>
* c-tree.h (struct lang_identifier): Replace global_value,
local_value members with symbol_value, tag_value. Kill
implicit_decl and limbo_value.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
C_MISSING_PROTOTYPE_WARNED): Kill.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE,
C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New.
(C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE.
(implicit_decl_warning, lookup_name_current_level,
record_function_scope_shadow): Don't prototype.
(pushdecl_function_level): Prototype.
* c-decl.c (truly_local_externals): New variable.
(struct binding_level): Adjust commentary.
(get_function_binding_level, clear_limbo_values,
record_function_scope_shadow): Kill.
(lookup_name_current_level, implicit_decl_warning): Are now static.
(any_external_decl, record_external_decl): New static functions.
(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.
(poplevel): Delete #if 0 block. Make externals invisible
instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
(duplicate-decls): For real parm decl after a forward decl,
set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
foo(...) { } with only a warning. Say whether a previous
declaration was implicit.
(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction
between global and local symbol values; they're all
IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
DECL_EXTERNAL decls, and use any_external_decl to check
against previous externals. Kill #if 0 blocks. Don't
tolerate error_mark_node being NULL.
(pushdecl_top_level): Handle only those cases which
Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with
C_DECL_IMPLICIT set. Recycle old decls, however they got
created.
(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
for C_DECL_INVISIBLE symbols.
(lookup_name_current_level): Likewise. Use chain_member.
(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.
(builtin_function): Use C_DECL_INVISIBLE.
(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
(identifier_global_value): Same. Must scan
global_binding_level in extremis.
* c-typeck.c (undeclared_variable): New static function, split
from build_external_ref.
(build_external_ref): Use DECL_CONTEXT, not
IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
an instance variable. Restructure for clarity.
* objc/objc-act.c: Use identifier_global_value, not
IDENTIFIER_GLOBAL_VALUE.
cp:
* decl.c: Update all calls to shadow_warning.
testsuite:
* gcc.c-torture/execute/builtin-noret-2.c: New.
* gcc.c-torture/execute/builtin-noret-2.x: New.
XFAIL builtin-noret-2.c at -O1 and above.
* gcc.dg/redecl.c: New.
* gcc.dg/Wshadow-1.c: Update error regexps.

for new data structures. Keep track of builtins that should be
made visible automatically.

expand_decl.
(grokparms): Return 0 if arg_types is error_mark_node.

reversed sense. Rewrite for new bindings structures. Do not
leave any decls in the scope, to prevent pop_scope from doing
contradictory things with them.

* c-tree.h: Forward declare struct c_binding. Declare
c_override_bindings_to_false. Update prototypes.
(struct lang_identifier): Update comments. Change fields to be
struct c_binding *.
(IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE)
(IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
(KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
(C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
* c-common.h: Update prototypes.
* c-decl.c (struct c_scope): Update commentary. Remove names,
names_last, parms, parms_last, tags, and shadowed fields. Add
bindings and depth fields.
(scope_freelist): Move to more appropriate location.
(c_print_identifier): Update for changes to struct lang_identifier.
(objc_mark_locals_volatile): Update for new bindings structures.
(global_bindings_p): Honor c_override_global_bindings_to_false.
(pushlevel): Rename to push_scope; take no arguments; use the
scope_freelist; initialize scope->depth and check for overflow.
(poplevel): Rename to pop_scope; totally rewritten for new bindings
structures.
(diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
Improve some commentary. Adjust handling of forward parm decls.
(merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
Preserve C_DECL_IN_EXTERNAL_SCOPE.
(warn_if_shadowing): Correct indentation. Improve diagnostics.
(pushdecl): Remove unnecessary assertion. Short-circuit anonymous
decls. Rewrite for new bindings structures. Improve commentary.
Eliminate the copy_node call.
(implicit_decl_warning): Use the "diag" idiom (as seen in
locate_old_decl) to reduce code duplication; call locate_old_decl
if appropriate. Relocate to remove need for forward declaration.
(implicitly_declare): Adjust for new bindings structures. Kludge
around Objective-C not-really-builtin functions.
(undeclared_variable): Improve diagnostics. If current_function_decl
is nonnull but current_function_scope is null, use current_scope.
Use bind.
(lookup_tag): Adjust for new bindings structures. Kludge around
Objective-C's tag declarations that wind up in the external scope.
(lookup_name): Adjust for new bindings structures. Kludge around
c-common.c's pseudo-typedefs that wind up in the external scope.
(lookup_name_current_level): Rename lookup_name_in_scope; take a
second argument indicating the scope to examine; rewrite for
new bindings structures.
(c_init_decl_processing): Adjust for renamed functions. Do not
initialize current_file_decl, first_builtin_decl, last_builtin_decl.
First scope pushed is the external scope, not the global scope.

for new data structures. Keep track of builtins that should be
made visible automatically.
