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. (IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE, C_DECL_IMPLICIT, C_DECL_ISNT_PROTOTYPE): New. (C_DECL_ANTICIPATED): Rename to C_DECL_INVISIBLE. (implicit_decl_warning, lookup_name_current_level, record_function_scope_shadow): Don't prototype. (pushdecl_function_level): Prototype. * c-decl.c (truly_local_externals): New variable. (struct binding_level): Adjust commentary. (get_function_binding_level, clear_limbo_values, record_function_scope_shadow): Kill. (lookup_name_current_level, implicit_decl_warning): Are now static. (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. cp: * decl.c: Update all calls to shadow_warning. testsuite: * gcc.c-torture/execute/builtin-noret-2.c: New. * gcc.c-torture/execute/builtin-noret-2.x: New.
