2320 * c-common.h: Update prototypes.
2321 * c-decl.c (struct c_scope): Update commentary. Remove names,
2322 names_last, parms, parms_last, tags, and shadowed fields. Add
2323 bindings and depth fields.
2324 (scope_freelist): Move to more appropriate location.
2325 (c_print_identifier): Update for changes to struct lang_identifier.
2326 (objc_mark_locals_volatile): Update for new bindings structures.
2327 (global_bindings_p): Honor c_override_global_bindings_to_false.
2328 (pushlevel): Rename to push_scope; take no arguments; use the
2329 scope_freelist; initialize scope->depth and check for overflow.
2330 (poplevel): Rename to pop_scope; totally rewritten for new bindings
2332 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
2333 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
2334 Improve some commentary. Adjust handling of forward parm decls.
2335 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
2336 Preserve C_DECL_IN_EXTERNAL_SCOPE.
2337 (warn_if_shadowing): Correct indentation. Improve diagnostics.
2338 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
2339 decls. Rewrite for new bindings structures. Improve commentary.
2340 Eliminate the copy_node call.
2341 (implicit_decl_warning): Use the "diag" idiom (as seen in
2342 locate_old_decl) to reduce code duplication; call locate_old_decl
2343 if appropriate. Relocate to remove need for forward declaration.
2344 (implicitly_declare): Adjust for new bindings structures. Kludge
2345 around Objective-C not-really-builtin functions.
2346 (undeclared_variable): Improve diagnostics. If current_function_decl
2347 is nonnull but current_function_scope is null, use current_scope.
2349 (lookup_tag): Adjust for new bindings structures. Kludge around
2350 Objective-C's tag declarations that wind up in the external scope.

2352 c-common.c's pseudo-typedefs that wind up in the external scope.
2353 (lookup_name_current_level): Rename lookup_name_in_scope; take a
2354 second argument indicating the scope to examine; rewrite for
2355 new bindings structures.
2356 (c_init_decl_processing): Adjust for renamed functions. Do not
2357 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
2358 First scope pushed is the external scope, not the global scope.
2359 (builtin_function): Use bind, not pushdecl. Adjust other bits
2360 for new data structures. Keep track of builtins that should be
2361 made visible automatically.
2362 (start_decl): Adjust diagnostics. Remove unnecessary call to
2364 (grokparms): Return 0 if arg_types is error_mark_node.
2365 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
2366 reversed sense. Rewrite for new bindings structures. Do not
2367 leave any decls in the scope, to prevent pop_scope from doing
2368 contradictory things with them.
2369 (finish_struct, finish_enum): Remove redundant diagnostics.
2370 (build_enumerator): Don't cascade diagnostics for error_mark_node.
2371 Mark location where -pedantic changes the meaning of the program.

2373 parameter decls into the function's scope structure using bind.

2401 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
2402 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
2403 correct loop over multiple translation units; call fatal_error if
2404 requested to compile more than one file at once. (This disables
2405 IMA temporarily - an up-front error being preferable to a crash.)
2406 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
2407 (all actions): Adjust calls to pushlevel/poplevel.
2408 (parsing_iso_function_signature): Delete.
2409 (extdef_1): Fold into extdef.
2410 (old_style_parm_decls_1): Fold into old_style_parm_decls. Don't

2414 commented-out productions.

2416 an empty TREE_LIST node. Adjust calls to get_parm_info.
2417 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
2418 to suppress -Wold-style-definition after this error.
2419 (c_parse_file): Don't clear the binding stack or call
2420 finish_fname_decls here. Correct comment.
2421 * c-typeck.c (same_translation_unit_p): Export.
2422 (common_type): Use c_override_global_bindings_to_false, not
2423 pushlevel/poplevel/declare_parm_level.
2424 * c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
2425 LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
