510 (clear_binding_level, lookup_tag_reverse): Kill.
511 (make_binding_level): Use ggc_alloc_cleared or memset.
512 (lookup_tag): Remove struct binding_level* parameter. All
513 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
514 current_binding_level->tags if asked for thislevel_only or if
515 we might have to diagnose "struct foo; union foo;"
516 (pushlevel): Ignore argument. Do not push another binding
517 level on the transition from the parameters to the top level
518 of the function body; just tweak the flags and proceed.
519 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
520 a function body, separate the parameter list from the
521 top-level local variables.
522 (set_block): Do nothing.
523 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
524 shadowed_tags if necessary.

528 an older decl in the same binding level.

531 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
532 (start_function): Don't set subblocks_tag_transparent.
533 (finish_function): Fix up the binding_level stack for totally
534 empty functions. Otherwise, don't call poplevel.
536 * c-common.c (shadow_warning): MANDATORY argument is no longer
537 necessary. Always use plain warning.
538 * c-common.h: Update to match.
540 * cfglayout.c (scope_to_insns_initialize): Clear block when we
541 hit the FUNCTION_DECL.

568 (poplevel): Delete #if 0 block. Make externals invisible
569 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
570 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
571 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
572 (duplicate-decls): For real parm decl after a forward decl,
573 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
574 foo(...) { } with only a warning. Say whether a previous
575 declaration was implicit.
576 (warn_if_shadowing): Now handles all shadowing, not just
577 local-over-local. Clarify comments.
578 (pushdecl): Rewritten. There is no longer a distinction
579 between global and local symbol values; they're all
580 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
581 DECL_EXTERNAL decls, and use any_external_decl to check
582 against previous externals. Kill #if 0 blocks. Don't
583 tolerate error_mark_node being NULL.

585 Objective C (the only user) needs.
586 (pushdecl_function_level): New function.
587 (implicitly_declare): Create ordinary decls with
588 C_DECL_IMPLICIT set. Recycle old decls, however they got

591 for C_DECL_INVISIBLE symbols.
592 (lookup_name_current_level): Likewise. Use chain_member.

596 (start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
597 Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
598 (store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
599 (identifier_global_value): Same. Must scan
600 global_binding_level in extremis.
602 * c-typeck.c (undeclared_variable): New static function, split
603 from build_external_ref.
604 (build_external_ref): Use DECL_CONTEXT, not
605 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
606 an instance variable. Restructure for clarity.
607 * objc/objc-act.c: Use identifier_global_value, not
608 IDENTIFIER_GLOBAL_VALUE.
