339a28b96a c-decl.c (struct binding_level): Add shadowed_tags and function_body... 
2003-04-10  Zack Weinberg  <zack@codesourcery.com>

	* c-decl.c (struct binding_level): Add shadowed_tags and
	function_body; remove this_block, tag_transparent, and
	subblocks_tag_transparent; update comments.
	(clear_binding_level, lookup_tag_reverse): Kill.
	(make_binding_level): Use ggc_alloc_cleared or memset.
	(lookup_tag): Remove struct binding_level* parameter.  All
	callers changed. Just look at IDENTIFIER_TAG_VALUE, and
	current_binding_level->tags if asked for thislevel_only or if
	we might have to diagnose "struct foo; union foo;"
	(pushlevel): Ignore argument.  Do not push another binding
	level on the transition from the parameters to the top level
	of the function body; just tweak the flags and proceed.
	(poplevel): Overhaul.  Clear IDENTIFIER_TAG_VALUEs; on exiting
	a function body, separate the parameter list from the
	top-level local variables.
	(set_block): Do nothing.
	(pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
	shadowed_tags if necessary.
	(warn_if_shadowing): Nuke the special case for local shadowing
	parameter.
	(pushdecl): Do not create a shadow entry if we are replacing
	an older decl in the same binding level.
	(pushdecl_function_level): Tweak for new way of indicating
	function scope.
	(shadow_tag_warned): Use TYPE_NAME, not	lookup_tag_reverse.
	(start_function): Don't set subblocks_tag_transparent.
	(finish_function): Fix up the binding_level stack for totally
	empty functions.  Otherwise, don't call poplevel.

	* c-common.c (shadow_warning): MANDATORY argument is no longer
	necessary.  Always use plain warning.
	* c-common.h: Update to match.

	* cfglayout.c (scope_to_insns_initialize): Clear block when we
	hit the FUNCTION_DECL.
	* function.c: Do not create cyclic tree structure.

2003-04-10  Zack Weinberg  <zack@codesourcery.com>

	* c-tree.h (struct lang_identifier): Replace global_value,
	local_value members with symbol_value, tag_value.  Kill
	implicit_decl and limbo_value.
	(IDENTIFIER_GLOBAL_VALUE, IDENTIFIER_LOCAL_VALUE,
	IDENTIFIER_LIMBO_VALUE, IDENTIFIER_IMPLICIT_DECL,
	C_MISSING_PROTOTYPE_WARNED): Kill.

	(any_external_decl, record_external_decl): New static functions.
	(clone_underlying type): Split out of pushdecl.
	(c_print_identifier): Update to match changes to struct
	lang_identifier.
	(poplevel): Delete #if 0 block.  Make externals invisible
	instead of clearing their IDENTIFIER_SYMBOL_VALUEs.  Don't
	call clear_limbo_values.  Refer to IDENTIFIER_SYMBOL_VALUE not
	IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
	(duplicate-decls): For real parm decl after a forward decl,
	set TREE_ASM_WRITTEN here.  Allow void foo(...) followed by
	foo(...) { } with only a warning.  Say whether a previous
	declaration was implicit.
	(warn_if_shadowing): Now handles all shadowing, not just
	local-over-local.  Clarify comments.
	(pushdecl): Rewritten.  There is no longer a distinction
	between global and local symbol values; they're all
	IDENTIFIER_SYMBOL_VALUE.  Call record_external_decl on all
	DECL_EXTERNAL decls, and use any_external_decl to check
	against previous externals.  Kill #if 0 blocks.  Don't
	tolerate error_mark_node being NULL.
	(pushdecl_top_level): Handle only those cases which
	Objective C (the only user) needs.
	(pushdecl_function_level): New function.
	(implicitly_declare): Create ordinary decls with
	C_DECL_IMPLICIT set.  Recycle old decls, however they got
	created.
	(lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
	for C_DECL_INVISIBLE symbols.
	(lookup_name_current_level): Likewise.  Use chain_member.
	(c_make_fname_decl): Don't muck with DECL_CONTEXT.
	Use pushdecl_function_level.
	(builtin_function): Use C_DECL_INVISIBLE.
	(start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
	Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
	(store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
	(identifier_global_value): Same.  Must scan
	global_binding_level in extremis.

	* c-typeck.c (undeclared_variable): New static function, split
	from build_external_ref.
	(build_external_ref): Use DECL_CONTEXT, not
	IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
	an instance variable.  Restructure for clarity.
	* objc/objc-act.c: Use identifier_global_value, not
	IDENTIFIER_GLOBAL_VALUE.
