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

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