9037 (make_binding_level): Use ggc_alloc_cleared or memset.
9038 (lookup_tag): Remove struct binding_level* parameter. All
9039 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
9040 current_binding_level->tags if asked for thislevel_only or if
9041 we might have to diagnose "struct foo; union foo;"
9042 (pushlevel): Ignore argument. Do not push another binding
9043 level on the transition from the parameters to the top level
9044 of the function body; just tweak the flags and proceed.
9045 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
9046 a function body, separate the parameter list from the
9047 top-level local variables.
9048 (set_block): Do nothing.

9050 shadowed_tags if necessary.

9057 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
9058 (start_function): Don't set subblocks_tag_transparent.
9059 (finish_function): Fix up the binding_level stack for totally
9060 empty functions. Otherwise, don't call poplevel.
9062 * c-common.c (shadow_warning): MANDATORY argument is no longer
9063 necessary. Always use plain warning.
9064 * c-common.h: Update to match.

9067 hit the FUNCTION_DECL.

9092 (c_print_identifier): Update to match changes to struct
9094 (poplevel): Delete #if 0 block. Make externals invisible
9095 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9096 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9097 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9098 (duplicate-decls): For real parm decl after a forward decl,
9099 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9100 foo(...) { } with only a warning. Say whether a previous
9101 declaration was implicit.
9102 (warn_if_shadowing): Now handles all shadowing, not just
9103 local-over-local. Clarify comments.
9104 (pushdecl): Rewritten. There is no longer a distinction
9105 between global and local symbol values; they're all
9106 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9107 DECL_EXTERNAL decls, and use any_external_decl to check
9108 against previous externals. Kill #if 0 blocks. Don't
9109 tolerate error_mark_node being NULL.
9110 (pushdecl_top_level): Handle only those cases which
9111 Objective C (the only user) needs.
9112 (pushdecl_function_level): New function.
9113 (implicitly_declare): Create ordinary decls with
9114 C_DECL_IMPLICIT set. Recycle old decls, however they got

9126 global_binding_level in extremis.
9128 * c-typeck.c (undeclared_variable): New static function, split
9129 from build_external_ref.

9134 IDENTIFIER_GLOBAL_VALUE.
