* c-tree.h: Forward declare struct c_binding. Declare c_override_bindings_to_false. Update prototypes. (struct lang_identifier): Update comments. Change fields to be struct c_binding *. (IDENTIFIER_SYMBOL_VALUE, IDENTIFIER_TAG_VALUE) (IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE) (KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete. (C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New. * c-common.h: Update prototypes. * c-decl.c (struct c_scope): Update commentary. Remove names, names_last, parms, parms_last, tags, and shadowed fields. Add bindings and depth fields. (scope_freelist): Move to more appropriate location. (c_print_identifier): Update for changes to struct lang_identifier. (objc_mark_locals_volatile): Update for new bindings structures. (global_bindings_p): Honor c_override_global_bindings_to_false. (pushlevel): Rename to push_scope; take no arguments; use the scope_freelist; initialize scope->depth and check for overflow. (poplevel): Rename to pop_scope; totally rewritten for new bindings structures. (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics. Improve some commentary. Adjust handling of forward parm decls. (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate. Preserve C_DECL_IN_EXTERNAL_SCOPE. (warn_if_shadowing): Correct indentation. Improve diagnostics. (pushdecl): Remove unnecessary assertion. Short-circuit anonymous decls. Rewrite for new bindings structures. Improve commentary. Eliminate the copy_node call. (implicit_decl_warning): Use the "diag" idiom (as seen in locate_old_decl) to reduce code duplication; call locate_old_decl if appropriate. Relocate to remove need for forward declaration. (implicitly_declare): Adjust for new bindings structures. Kludge around Objective-C not-really-builtin functions. (undeclared_variable): Improve diagnostics. If current_function_decl is nonnull but current_function_scope is null, use current_scope. Use bind. (lookup_tag): Adjust for new bindings structures. Kludge around Objective-C's tag declarations that wind up in the external scope. (lookup_name): Adjust for new bindings structures. Kludge around c-common.c's pseudo-typedefs that wind up in the external scope. (lookup_name_current_level): Rename lookup_name_in_scope; take a second argument indicating the scope to examine; rewrite for new bindings structures. (c_init_decl_processing): Adjust for renamed functions. Do not initialize current_file_decl, first_builtin_decl, last_builtin_decl. First scope pushed is the external scope, not the global scope. (builtin_function): Use bind, not pushdecl. Adjust other bits for new data structures. Keep track of builtins that should be made visible automatically. (start_decl): Adjust diagnostics. Remove unnecessary call to expand_decl. (grokparms): Return 0 if arg_types is error_mark_node. (get_parm_info): Rename "void_at_end" argument to "ellipsis", with reversed sense. Rewrite for new bindings structures. Do not leave any decls in the scope, to prevent pop_scope from doing contradictory things with them. (finish_struct, finish_enum): Remove redundant diagnostics. (build_enumerator): Don't cascade diagnostics for error_mark_node. Mark location where -pedantic changes the meaning of the program. (store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the parameter decls into the function's scope structure using bind. Warn here about function definitions in the wrong style. Adjust diagnostics. (store_parm_decls): Correct the determination of whether a function was defined with a prototype. (c_write_global_declarations): Operate on all file decls and on the external scope. Split body of the loop to... (c_write_global_declarations_1): ... this new function, to avoid code duplication.

Improve diagnostics and commentary. * c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to pushlevel/poplevel respectively. (c_objc_common_finish_file): Don't call merge_translation_unit_decls. * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED. Warn about YYDEBUG not being defined only if -dy. Remove no-longer- correct loop over multiple translation units; call fatal_error if requested to compile more than one file at once. (This disables IMA temporarily - an up-front error being preferable to a crash.) * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope. (all actions): Adjust calls to pushlevel/poplevel. (parsing_iso_function_signature): Delete. (extdef_1): Fold into extdef. (old_style_parm_decls_1): Fold into old_style_parm_decls. Don't warn here about function definitions in the wrong style. (after_tyle_declarator, parm_declarator_starttypename) (parm_declarator_nostarttypename, notype_declarator): Remove commented-out productions. (parmlist_1, parmlist_2): Use make_node, not tree_cons, to create an empty TREE_LIST node. Adjust calls to get_parm_info. (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node to suppress -Wold-style-definition after this error. (c_parse_file): Don't clear the binding stack or call finish_fname_decls here. Correct comment. * c-typeck.c (same_translation_unit_p): Export. (common_type): Use c_override_global_bindings_to_false, not pushlevel/poplevel/declare_parm_level. * c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK, LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK, and LANG_HOOKS_GETDECLS with do-nothing stubs. * objc/objc-lang.c: Likewise. * objc/objc-act.c: Adjust all calls to pushlevel, poplevel, get_parm_info. (OBJC_VOID_AT_END): Delete; replace all uses with void_list_node.

(push_file_scope, pop_file_scope): New stubs. * parser.c (c_parse_file): Call sorry() here if called more than once. testsuite: * gcc.dg/Wold-style-definition-1.c, gcc.dg/builtins-30.c * gcc.dg/unused-4.c, gcc.dg/noncompile/label-1.c * gcc.dg/noncompile/label-lineno-1.c, objc.dg/naming-1.m: Adjust error regexps. * gcc.dg/Wshadow-2.c, gcc.dg/noncompile/incomplete-3.c * gcc.dg/noncompile/undeclared-1.c: New test cases. * gcc.dg/decl-5.c, gcc.dg/redecl-1.c: Remove XFAIL. * gcc.dg/local1.c: Add explanatory comment.
