1017 (make_binding_level): Use ggc_alloc_cleared or memset.
1018 (lookup_tag): Remove struct binding_level* parameter. All
1019 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
1020 current_binding_level->tags if asked for thislevel_only or if
1021 we might have to diagnose "struct foo; union foo;"
1022 (pushlevel): Ignore argument. Do not push another binding
1023 level on the transition from the parameters to the top level
1024 of the function body; just tweak the flags and proceed.
1025 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
1026 a function body, separate the parameter list from the
1027 top-level local variables.
1028 (set_block): Do nothing.
1029 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
1030 shadowed_tags if necessary.

1034 an older decl in the same binding level.
1035 (pushdecl_function_level): Tweak for new way of indicating
1037 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
1038 (start_function): Don't set subblocks_tag_transparent.
1039 (finish_function): Fix up the binding_level stack for totally
1040 empty functions. Otherwise, don't call poplevel.
1042 * c-common.c (shadow_warning): MANDATORY argument is no longer
1043 necessary. Always use plain warning.
1044 * c-common.h: Update to match.
1046 * cfglayout.c (scope_to_insns_initialize): Clear block when we
1047 hit the FUNCTION_DECL.
1048 * function.c: Do not create cyclic tree structure.

1072 (c_print_identifier): Update to match changes to struct
1074 (poplevel): Delete #if 0 block. Make externals invisible
1075 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
1076 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
1077 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
1078 (duplicate-decls): For real parm decl after a forward decl,
1079 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
1080 foo(...) { } with only a warning. Say whether a previous
1081 declaration was implicit.
1082 (warn_if_shadowing): Now handles all shadowing, not just
1083 local-over-local. Clarify comments.
1084 (pushdecl): Rewritten. There is no longer a distinction
1085 between global and local symbol values; they're all
1086 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
1087 DECL_EXTERNAL decls, and use any_external_decl to check
1088 against previous externals. Kill #if 0 blocks. Don't
1089 tolerate error_mark_node being NULL.
1090 (pushdecl_top_level): Handle only those cases which
1091 Objective C (the only user) needs.
1092 (pushdecl_function_level): New function.
1093 (implicitly_declare): Create ordinary decls with
1094 C_DECL_IMPLICIT set. Recycle old decls, however they got

1103 Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
1104 (store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
1105 (identifier_global_value): Same. Must scan
1106 global_binding_level in extremis.
1108 * c-typeck.c (undeclared_variable): New static function, split
1109 from build_external_ref.
1110 (build_external_ref): Use DECL_CONTEXT, not
1111 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
1112 an instance variable. Restructure for clarity.

1114 IDENTIFIER_GLOBAL_VALUE.
