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.

/* Each c_scope structure describes the complete contents of one scope.
|
|

|
|
|
Three scopes are distinguished specially: the innermost or current
|
|
|
|
|
|
scope, the innermost function scope, and the outermost or file scope.
|
|
|
|
|
|
|
|
|
|
|
|
Most declarations are recorded in the current 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.
|
|
|
|
|
|
|
|
|
|
|
|
Being in the global scope (current_scope == global_scope) causes
|
|
|
|
|
|
special behavior in several places below. Also, under some
|
|
|
|
|
|
conditions the Objective-C front end records declarations in the
|
|
|
|
|
|
global scope even though that isn't the current scope.
|
|
|
|
|
|
|
|
|
|
|
|
The order of the names, parms, and blocks lists matters, and they
|
|
|
|
|
|
are frequently appended to. To avoid having to walk all the way to
|
|
|
|
|
|
the end of the list on each insertion, or reverse the lists later,
|
|
|
|
|
|
we maintain a pointer to the last list entry for each of the lists.

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.

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.

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

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

(warn_if_shadowing): Now handles all shadowing, not just
local-over-local. Clarify comments.
(pushdecl): Rewritten. There is no longer a distinction

Objective C (the only user) needs.
(pushdecl_function_level): New function.
(implicitly_declare): Create ordinary decls with

* 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...
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>

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

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.

* 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.

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-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.

/* 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.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.

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.

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.

* 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

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.

(c_make_fname_decl): Don't muck with DECL_CONTEXT.
Use pushdecl_function_level.

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.

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.

* 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-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-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.

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"

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.

declaration to top of function, restructure code reordering
DECL_ARGUMENTS.
(store_parm_decls): No need to save and restore warn_shadow.

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.

(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.

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:

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

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.

(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.

/* Given declspecs and a declarator,
|
|
|
|
|
|
determine the name and type of the object declared
|
|
|
|
|
|
and construct a ..._DECL node for it.
|
|
|
|
|
|
(In one case we can return a ..._TYPE node instead.
|
|
|
|
|
|
For invalid input we sometimes return 0.)
|
|
|
|
|
|
|
|
|
|
|
|
DECLSPECS is a chain of tree_list nodes whose value fields
|
|
|
|
|
|
are the storage classes and type specifiers.
|
|
|
|
|
|
|
|
|
|
|
|
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.
|
2002-02-02 01:14:41 +01:00
|
|
|
|
BITFIELD for a field with specified width.
|
1992-02-13 23:21:26 +01:00
|
|
|
|
INITIALIZED is 1 if the decl has an initializer.
|
|
|
|
|
|
|
|
|
|
|
|
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. */

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.

/* 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.
|
|
|
|
|
|
|
|
|
|
|
|
Store in `last_function_parms' a chain of the decls of parms.
|
|
|
|
|
|
Also store in `last_function_parm_tags' a chain of the struct, union,
|
|
|
|
|
|
and enum tags declared among the parms.
|
|
|
|
|
|
|
|
|
|
|
|
Return a list of arg types to use in the FUNCTION_TYPE for this function.
|
|
|
|
|
|
|
|
|
|
|
|
FUNCDEF_FLAG is nonzero for a function definition, 0 for
|
|
|
|
|
|
a mere declaration. A nonempty identifier-list gets an error message
|
|
|
|
|

when FUNCDEF_FLAG is zero. */

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.

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.

* c-common.c, c-decl.c, c-lang.c, c-lex.c, c-parse.in, c-pragma.c,

functions obsoleted by GC, such as push_obstacks_nochange,

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.

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...
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

Integrated preprocessor.
top level:
* Makefile.in: Remove all references to c-parse.gperf,
c-gperf.h, and c-parse.h. Remove -d from yacc command line
generating c-parse.c. Update dependencies.
* c-parse.gperf, c-gperf.h: Delete.
* c-common.c: Don't define parse_options, cpp_token, yy_cur,
yy_lim, or yy_get_token. Don't define get_directive_line if
USE_CPPLIB.
* c-common.h: Add multiple include guard. Define RID values
for every keyword in C, C++, and Objective C. Put all the
modifiers first.
(struct c_fileinfo, get_fileinfo, dump_time_statistics): New.
* c-decl.c (c_decode_option): Handle -lang-objc here.
(print_lang_identifier): Handle C_IS_RESERVED_WORD case.
(grokdeclarator): Adjust for new RID scheme.
(extract_interface_info): New stub.
* c-lang.c: Don't declare yy_cur or parse_options.
(lang_init_options): Call cpp_init. Don't call
cpp_options_init.
(lang_init): Don't call check_newline if USE_CPPLIB.
* c-lex.c: Don't include c-parse.h. Do include timevar.h.
Elide lots of unnecessary code if USE_CPPLIB. Delete code
rendered unnecessary by new architecture. Move routines not
shared with C++ to c-parse.in. Maintain a local idea of the
line number. Handle C++ as well as C.
[USE_CPPLIB]: Declare and register callbacks for #ident and
for entering/leaving files.
(init_c_lex, c_lex): Are now the entry points to this file.
(check_newline): Break out directive handling to
process_directive.
(read_ucs, is_extended_char, utf8_extend_token): Moved here
from C++ front end.
(readescape, parse_float): Overhaul.
(lex_number, lex_string, lex_charconst): Break out of c_lex
(n'ee yylex).
(get_fileinfo, update_header_times, dump_one_header,
dump_time_statistics): New and/or moved here from C++.
Support per-file data needed by C++ and per-header timing
statistics (C++ only, at the moment).
* c-lex.h: Update prototypes. Add multiple include guard.
* c-tree.h (struct lang_identifier): Add rid_code field.
(C_IS_RESERVED_WORD, C_RID_CODE): New.
* c-parse.in: Include c-pragma.h. Remove unnecesary calls to
reinit_parse_for_function and/or position_after_white_space.
(save_filename, save_lineno): Look ahead before saving.
(label -> identifier ':'): Save file and line before shifting ':'.
(reservedwords): No need to call get_identifier.
(init_parse, finish_parse, yyerror, yylex, yyprint,
make_pointer_declarator): Are now here for C/ObjC.
(rid_to_yy): Conversion table from RID constants to Yacc codes.
* c-pragma.c: Rewrite parsing logic to fit with cpplib's
#pragma registry. Provide dummy implementation of that
interface if !USE_CPPLIB.
* c-pragma.h: Update to match.
* flags.h: Add multiple include guard.
(flag_detailed_statistics): Moved here from C++.
* toplev.c: Define flag_detailed_statistics.
* gcc.c (C specs): Use %(trad_capable_cpp) for -E|-M|-MM case
#if USE_CPPLIB.
* timevar.def (TV_CPP, TV_LEX): New.
* timevar.h: Add multiple include guard.
* objc/lang-specs.h: Use %(trad_capable_cpp) for -E|-M|-MM case
#if USE_CPPLIB.
* objc/objc-act.c: Don't mention yy_cur or parse_options.
Initialize cpplib properly. Force lineno to 0 after first
call to check_newline. Don't handle -lang-objc here.
Move forget_protocol_qualifiers and remember_protocol_qualifiers here.
cp:
* Make-lang.in, Makefile.in: Remove all references to input.c,
gxx.gperf, and hash.h. Add ../c-lex.o to C_OBJS.
* gxx.gperf, hash.h, input.c: Delete.
* lang-specs.h: Pass -lang-c++ to cc1plus so cpplib is
initialized properly.
* class.c (fixup_pending_inline): Take a tree, not a
struct pending_inline *. All callers changed.
(init_class_processing): Set RID_PUBLIC, RID_PRIVATE,
RID_PROTECTED entries in ridpointers[] array here.
* decl.c (duplicate_decls): Do not refer to struct
pending_inline.
(record_builtin_type, init_decl_processing): Use RID_MAX not
CP_RID_MAX.
(grokdeclarator): Use C_IS_RESERVED_WORD.
* decl2.c (lang_decode_option): Ignore -lang-c++ for sake of
cpplib.
(grok_x_components): Do not inspect pending_inlines chain.
* cp-tree.h (struct lang_identifier): Add rid_code entry.
(C_IS_RESERVED_WORD, C_RID_CODE, C_RID_YYCODE): New.
(flag_no_gnu_keywords, flag_operator_names, rid_to_yy): Declare.
(DEFARG_LENGTH, struct pending_inline, TIME_IDENTIFIER_TIME,
TIME_IDENTIFIER_FILEINFO): Kill.
Update prototypes.
* lex.h: Expunge cp_rid. Rewrite RIDBIT macros to use just a
single 32-bit word.
* parse.y: Call do_pending_inlines unconditionally.
reinit_parse_for_method is now snarf_method. fn.defpen is no
longer necessary. Remove unnecessary <itype> annotation on
SCOPE. Do not refer to end_of_file or struct pending_inline.
* semantics.c (begin_inline_definitions): Call
do_pending_inlines unconditionally.
* lex.c: Remove all code now shared with C front end.
Initialize cpplib properly if USE_CPPLIB. Put reserved words
into the get_identifier table. Rewrite pragma handling to
work with the registry. Move code to save tokens for later
processing to spew.c.
* spew.c: Rewrite everything in terms of token streams instead
of text. Move routines here from lex.c / input.c as

* c-common.c: Don't define parse_options, cpp_token, yy_cur,
yy_lim, or yy_get_token. Don't define get_directive_line if
USE_CPPLIB.

for every keyword in C, C++, and Objective C. Put all the
modifiers first.
(struct c_fileinfo, get_fileinfo, dump_time_statistics): New.

cp:
* Make-lang.in, Makefile.in: Remove all references to input.c,
gxx.gperf, and hash.h. Add ../c-lex.o to C_OBJS.

longer necessary. Remove unnecessary <itype> annotation on
SCOPE. Do not refer to end_of_file or struct pending_inline.
* semantics.c (begin_inline_definitions): Call
do_pending_inlines unconditionally.

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.
(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,

(clone_underlying type): Split out of pushdecl.
(c_print_identifier): Update to match changes to struct
lang_identifier.

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

Use pushdecl_function_level.

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:

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,
