10808 (lookup_tag): Remove struct binding_level* parameter. All
10809 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
10810 current_binding_level->tags if asked for thislevel_only or if
10811 we might have to diagnose "struct foo; union foo;"
10812 (pushlevel): Ignore argument. Do not push another binding
10813 level on the transition from the parameters to the top level
10814 of the function body; just tweak the flags and proceed.
10815 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
10816 a function body, separate the parameter list from the
10817 top-level local variables.
10818 (set_block): Do nothing.
10819 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
10820 shadowed_tags if necessary.
10821 (warn_if_shadowing): Nuke the special case for local shadowing
10823 (pushdecl): Do not create a shadow entry if we are replacing
10824 an older decl in the same binding level.
10825 (pushdecl_function_level): Tweak for new way of indicating
10827 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
10828 (start_function): Don't set subblocks_tag_transparent.
10829 (finish_function): Fix up the binding_level stack for totally
10830 empty functions. Otherwise, don't call poplevel.
10832 * c-common.c (shadow_warning): MANDATORY argument is no longer
10833 necessary. Always use plain warning.
10834 * c-common.h: Update to match.
10836 * cfglayout.c (scope_to_insns_initialize): Clear block when we
10837 hit the FUNCTION_DECL.
10838 * function.c: Do not create cyclic tree structure.

10862 (c_print_identifier): Update to match changes to struct
10864 (poplevel): Delete #if 0 block. Make externals invisible
10865 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10866 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10867 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10868 (duplicate-decls): For real parm decl after a forward decl,
10869 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10870 foo(...) { } with only a warning. Say whether a previous
10871 declaration was implicit.
10872 (warn_if_shadowing): Now handles all shadowing, not just
10873 local-over-local. Clarify comments.
10874 (pushdecl): Rewritten. There is no longer a distinction
10875 between global and local symbol values; they're all
10876 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10877 DECL_EXTERNAL decls, and use any_external_decl to check
10878 against previous externals. Kill #if 0 blocks. Don't
10879 tolerate error_mark_node being NULL.
10880 (pushdecl_top_level): Handle only those cases which
10881 Objective C (the only user) needs.
10882 (pushdecl_function_level): New function.
10883 (implicitly_declare): Create ordinary decls with
10884 C_DECL_IMPLICIT set. Recycle old decls, however they got

10896 global_binding_level in extremis.
10898 * c-typeck.c (undeclared_variable): New static function, split
10899 from build_external_ref.

10902 an instance variable. Restructure for clarity.

10904 IDENTIFIER_GLOBAL_VALUE.
