9470 (make_binding_level): Use ggc_alloc_cleared or memset.
9471 (lookup_tag): Remove struct binding_level* parameter. All
9472 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
9473 current_binding_level->tags if asked for thislevel_only or if
9474 we might have to diagnose "struct foo; union foo;"
9475 (pushlevel): Ignore argument. Do not push another binding
9476 level on the transition from the parameters to the top level
9477 of the function body; just tweak the flags and proceed.
9478 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
9479 a function body, separate the parameter list from the
9480 top-level local variables.
9481 (set_block): Do nothing.
9482 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
9483 shadowed_tags if necessary.
9484 (warn_if_shadowing): Nuke the special case for local shadowing
9486 (pushdecl): Do not create a shadow entry if we are replacing
9487 an older decl in the same binding level.
9488 (pushdecl_function_level): Tweak for new way of indicating
9490 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
9491 (start_function): Don't set subblocks_tag_transparent.
9492 (finish_function): Fix up the binding_level stack for totally
9493 empty functions. Otherwise, don't call poplevel.
9495 * c-common.c (shadow_warning): MANDATORY argument is no longer
9496 necessary. Always use plain warning.
9497 * c-common.h: Update to match.
9499 * cfglayout.c (scope_to_insns_initialize): Clear block when we
9500 hit the FUNCTION_DECL.
9501 * function.c: Do not create cyclic tree structure.

9524 (clone_underlying type): Split out of pushdecl.
9525 (c_print_identifier): Update to match changes to struct
9527 (poplevel): Delete #if 0 block. Make externals invisible
9528 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
9529 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
9530 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
9531 (duplicate-decls): For real parm decl after a forward decl,
9532 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
9533 foo(...) { } with only a warning. Say whether a previous
9534 declaration was implicit.
9535 (warn_if_shadowing): Now handles all shadowing, not just
9536 local-over-local. Clarify comments.
9537 (pushdecl): Rewritten. There is no longer a distinction
9538 between global and local symbol values; they're all
9539 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
9540 DECL_EXTERNAL decls, and use any_external_decl to check
9541 against previous externals. Kill #if 0 blocks. Don't
9542 tolerate error_mark_node being NULL.
9543 (pushdecl_top_level): Handle only those cases which
9544 Objective C (the only user) needs.
9545 (pushdecl_function_level): New function.
9546 (implicitly_declare): Create ordinary decls with
9547 C_DECL_IMPLICIT set. Recycle old decls, however they got
9549 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
9550 for C_DECL_INVISIBLE symbols.
9551 (lookup_name_current_level): Likewise. Use chain_member.

9555 (start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
9556 Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
9557 (store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
9558 (identifier_global_value): Same. Must scan
9559 global_binding_level in extremis.
9561 * c-typeck.c (undeclared_variable): New static function, split
9562 from build_external_ref.
9563 (build_external_ref): Use DECL_CONTEXT, not
9564 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
9565 an instance variable. Restructure for clarity.
9566 * objc/objc-act.c: Use identifier_global_value, not
9567 IDENTIFIER_GLOBAL_VALUE.
