6784 (make_binding_level): Use ggc_alloc_cleared or memset.
6785 (lookup_tag): Remove struct binding_level* parameter. All
6786 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
6787 current_binding_level->tags if asked for thislevel_only or if
6788 we might have to diagnose "struct foo; union foo;"
6789 (pushlevel): Ignore argument. Do not push another binding
6790 level on the transition from the parameters to the top level
6791 of the function body; just tweak the flags and proceed.
6792 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
6793 a function body, separate the parameter list from the
6794 top-level local variables.
6795 (set_block): Do nothing.
6796 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
6797 shadowed_tags if necessary.
6798 (warn_if_shadowing): Nuke the special case for local shadowing
6800 (pushdecl): Do not create a shadow entry if we are replacing
6801 an older decl in the same binding level.
6802 (pushdecl_function_level): Tweak for new way of indicating
6804 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
6805 (start_function): Don't set subblocks_tag_transparent.
6806 (finish_function): Fix up the binding_level stack for totally
6807 empty functions. Otherwise, don't call poplevel.
6809 * c-common.c (shadow_warning): MANDATORY argument is no longer
6810 necessary. Always use plain warning.
6811 * c-common.h: Update to match.
6813 * cfglayout.c (scope_to_insns_initialize): Clear block when we
6814 hit the FUNCTION_DECL.
6815 * function.c: Do not create cyclic tree structure.

6838 (clone_underlying type): Split out of pushdecl.
6839 (c_print_identifier): Update to match changes to struct
6841 (poplevel): Delete #if 0 block. Make externals invisible
6842 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
6843 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
6844 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
6845 (duplicate-decls): For real parm decl after a forward decl,
6846 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
6847 foo(...) { } with only a warning. Say whether a previous
6848 declaration was implicit.
6849 (warn_if_shadowing): Now handles all shadowing, not just
6850 local-over-local. Clarify comments.
6851 (pushdecl): Rewritten. There is no longer a distinction
6852 between global and local symbol values; they're all
6853 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
6854 DECL_EXTERNAL decls, and use any_external_decl to check
6855 against previous externals. Kill #if 0 blocks. Don't
6856 tolerate error_mark_node being NULL.
6857 (pushdecl_top_level): Handle only those cases which
6858 Objective C (the only user) needs.
6859 (pushdecl_function_level): New function.
6860 (implicitly_declare): Create ordinary decls with
6861 C_DECL_IMPLICIT set. Recycle old decls, however they got
6863 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
6864 for C_DECL_INVISIBLE symbols.
6865 (lookup_name_current_level): Likewise. Use chain_member.

6869 (start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
6870 Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
6871 (store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
6872 (identifier_global_value): Same. Must scan
6873 global_binding_level in extremis.
6875 * c-typeck.c (undeclared_variable): New static function, split
6876 from build_external_ref.
6877 (build_external_ref): Use DECL_CONTEXT, not
6878 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
6879 an instance variable. Restructure for clarity.
6880 * objc/objc-act.c: Use identifier_global_value, not
6881 IDENTIFIER_GLOBAL_VALUE.
