13003 (make_binding_level): Use ggc_alloc_cleared or memset.
13004 (lookup_tag): Remove struct binding_level* parameter. All
13005 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
13006 current_binding_level->tags if asked for thislevel_only or if
13007 we might have to diagnose "struct foo; union foo;"
13008 (pushlevel): Ignore argument. Do not push another binding
13009 level on the transition from the parameters to the top level
13010 of the function body; just tweak the flags and proceed.
13011 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
13012 a function body, separate the parameter list from the
13013 top-level local variables.
13014 (set_block): Do nothing.
13015 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
13016 shadowed_tags if necessary.
13017 (warn_if_shadowing): Nuke the special case for local shadowing
13019 (pushdecl): Do not create a shadow entry if we are replacing
13020 an older decl in the same binding level.
13021 (pushdecl_function_level): Tweak for new way of indicating
13023 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
13024 (start_function): Don't set subblocks_tag_transparent.
13025 (finish_function): Fix up the binding_level stack for totally
13026 empty functions. Otherwise, don't call poplevel.
13028 * c-common.c (shadow_warning): MANDATORY argument is no longer
13029 necessary. Always use plain warning.
13030 * c-common.h: Update to match.
13032 * cfglayout.c (scope_to_insns_initialize): Clear block when we
13033 hit the FUNCTION_DECL.
13034 * function.c: Do not create cyclic tree structure.

13056 (any_external_decl, record_external_decl): New static functions.
13057 (clone_underlying type): Split out of pushdecl.
13058 (c_print_identifier): Update to match changes to struct
13060 (poplevel): Delete #if 0 block. Make externals invisible
13061 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
13062 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
13063 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
13064 (duplicate-decls): For real parm decl after a forward decl,
13065 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
13066 foo(...) { } with only a warning. Say whether a previous
13067 declaration was implicit.
13068 (warn_if_shadowing): Now handles all shadowing, not just
13069 local-over-local. Clarify comments.
13070 (pushdecl): Rewritten. There is no longer a distinction
13071 between global and local symbol values; they're all
13072 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
13073 DECL_EXTERNAL decls, and use any_external_decl to check
13074 against previous externals. Kill #if 0 blocks. Don't
13075 tolerate error_mark_node being NULL.
13076 (pushdecl_top_level): Handle only those cases which
13077 Objective C (the only user) needs.
13078 (pushdecl_function_level): New function.
13079 (implicitly_declare): Create ordinary decls with
13080 C_DECL_IMPLICIT set. Recycle old decls, however they got
13082 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
13083 for C_DECL_INVISIBLE symbols.
13084 (lookup_name_current_level): Likewise. Use chain_member.
13085 (c_make_fname_decl): Don't muck with DECL_CONTEXT.

13091 (identifier_global_value): Same. Must scan
13092 global_binding_level in extremis.
13094 * c-typeck.c (undeclared_variable): New static function, split
13095 from build_external_ref.
13096 (build_external_ref): Use DECL_CONTEXT, not
13097 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
13098 an instance variable. Restructure for clarity.

13100 IDENTIFIER_GLOBAL_VALUE.
