5423 (make_binding_level): Use ggc_alloc_cleared or memset.
5424 (lookup_tag): Remove struct binding_level* parameter. All
5425 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
5426 current_binding_level->tags if asked for thislevel_only or if
5427 we might have to diagnose "struct foo; union foo;"
5428 (pushlevel): Ignore argument. Do not push another binding
5429 level on the transition from the parameters to the top level
5430 of the function body; just tweak the flags and proceed.
5431 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
5432 a function body, separate the parameter list from the
5433 top-level local variables.
5434 (set_block): Do nothing.

5436 shadowed_tags if necessary.

5443 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
5444 (start_function): Don't set subblocks_tag_transparent.
5445 (finish_function): Fix up the binding_level stack for totally
5446 empty functions. Otherwise, don't call poplevel.
5448 * c-common.c (shadow_warning): MANDATORY argument is no longer
5449 necessary. Always use plain warning.
5450 * c-common.h: Update to match.

5453 hit the FUNCTION_DECL.

5478 (c_print_identifier): Update to match changes to struct
5480 (poplevel): Delete #if 0 block. Make externals invisible
5481 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
5482 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
5483 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
5484 (duplicate-decls): For real parm decl after a forward decl,
5485 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
5486 foo(...) { } with only a warning. Say whether a previous
5487 declaration was implicit.
5488 (warn_if_shadowing): Now handles all shadowing, not just
5489 local-over-local. Clarify comments.
5490 (pushdecl): Rewritten. There is no longer a distinction
5491 between global and local symbol values; they're all
5492 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
5493 DECL_EXTERNAL decls, and use any_external_decl to check
5494 against previous externals. Kill #if 0 blocks. Don't
5495 tolerate error_mark_node being NULL.

5497 Objective C (the only user) needs.
5498 (pushdecl_function_level): New function.
5499 (implicitly_declare): Create ordinary decls with

5515 from build_external_ref.

5520 IDENTIFIER_GLOBAL_VALUE.
