10439 (make_binding_level): Use ggc_alloc_cleared or memset.
10440 (lookup_tag): Remove struct binding_level* parameter. All
10441 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
10442 current_binding_level->tags if asked for thislevel_only or if
10443 we might have to diagnose "struct foo; union foo;"
10444 (pushlevel): Ignore argument. Do not push another binding
10445 level on the transition from the parameters to the top level
10446 of the function body; just tweak the flags and proceed.
10447 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
10448 a function body, separate the parameter list from the
10449 top-level local variables.
10450 (set_block): Do nothing.
10451 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
10452 shadowed_tags if necessary.

10459 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
10460 (start_function): Don't set subblocks_tag_transparent.
10461 (finish_function): Fix up the binding_level stack for totally
10462 empty functions. Otherwise, don't call poplevel.

10465 necessary. Always use plain warning.
10466 * c-common.h: Update to match.

10469 hit the FUNCTION_DECL.

10493 (clone_underlying type): Split out of pushdecl.
10494 (c_print_identifier): Update to match changes to struct
10496 (poplevel): Delete #if 0 block. Make externals invisible
10497 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
10498 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
10499 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
10500 (duplicate-decls): For real parm decl after a forward decl,
10501 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
10502 foo(...) { } with only a warning. Say whether a previous
10503 declaration was implicit.
10504 (warn_if_shadowing): Now handles all shadowing, not just
10505 local-over-local. Clarify comments.
10506 (pushdecl): Rewritten. There is no longer a distinction
10507 between global and local symbol values; they're all
10508 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
10509 DECL_EXTERNAL decls, and use any_external_decl to check
10510 against previous externals. Kill #if 0 blocks. Don't
10511 tolerate error_mark_node being NULL.
10512 (pushdecl_top_level): Handle only those cases which
10513 Objective C (the only user) needs.
10514 (pushdecl_function_level): New function.
10515 (implicitly_declare): Create ordinary decls with
10516 C_DECL_IMPLICIT set. Recycle old decls, however they got

10531 from build_external_ref.
10532 (build_external_ref): Use DECL_CONTEXT, not

10536 IDENTIFIER_GLOBAL_VALUE.
