6397 (make_binding_level): Use ggc_alloc_cleared or memset.
6398 (lookup_tag): Remove struct binding_level* parameter. All
6399 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
6400 current_binding_level->tags if asked for thislevel_only or if
6401 we might have to diagnose "struct foo; union foo;"
6402 (pushlevel): Ignore argument. Do not push another binding
6403 level on the transition from the parameters to the top level
6404 of the function body; just tweak the flags and proceed.
6405 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
6406 a function body, separate the parameter list from the
6407 top-level local variables.
6408 (set_block): Do nothing.

6410 shadowed_tags if necessary.

6417 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
6418 (start_function): Don't set subblocks_tag_transparent.
6419 (finish_function): Fix up the binding_level stack for totally
6420 empty functions. Otherwise, don't call poplevel.
6422 * c-common.c (shadow_warning): MANDATORY argument is no longer
6423 necessary. Always use plain warning.
6424 * c-common.h: Update to match.

6427 hit the FUNCTION_DECL.

6452 (c_print_identifier): Update to match changes to struct
6454 (poplevel): Delete #if 0 block. Make externals invisible
6455 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
6456 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
6457 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
6458 (duplicate-decls): For real parm decl after a forward decl,
6459 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
6460 foo(...) { } with only a warning. Say whether a previous
6461 declaration was implicit.
6462 (warn_if_shadowing): Now handles all shadowing, not just
6463 local-over-local. Clarify comments.
6464 (pushdecl): Rewritten. There is no longer a distinction
6465 between global and local symbol values; they're all
6466 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
6467 DECL_EXTERNAL decls, and use any_external_decl to check
6468 against previous externals. Kill #if 0 blocks. Don't
6469 tolerate error_mark_node being NULL.
6470 (pushdecl_top_level): Handle only those cases which
6471 Objective C (the only user) needs.
6472 (pushdecl_function_level): New function.
6473 (implicitly_declare): Create ordinary decls with
6474 C_DECL_IMPLICIT set. Recycle old decls, however they got

6483 Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
6484 (store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
6485 (identifier_global_value): Same. Must scan
6486 global_binding_level in extremis.
6488 * c-typeck.c (undeclared_variable): New static function, split
6489 from build_external_ref.

6494 IDENTIFIER_GLOBAL_VALUE.
