+ 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.

+ * 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.
+ (generate_forward_declaration_to_string_table): Delete.
+ * objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.
+
+ * coverage.c (create_coverage): Don't pushdecl anything.
+ * langhooks.c (lhd_clear_binding_stack): Call
+ lang_hooks.decls.poplevel, not poplevel.
+ * tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
+ circular list rather than going into an infinite loop.

+ from single word shifts, use a new register target if the provided
+ target is not a REG already.
