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.

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.

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. + 2004-03-23 Olivier Hainque <hainque@act-europe.fr> - * optabs.c (expand_binop): When synthesizing double word rotates - from single word shifts, use a new register target if the provided - target is not a REG already. + * optabs.c (expand_binop): When synthesizing double word rotates + from single word shifts, use a new register target if the provided + target is not a REG already. 2004-03-23 Richard Kenner <kenner@vlsi1.ultra.nyu.edu> @@ -198,8 +331,8 @@ * frontends.texi: Add missing line. 2004-03-21 Zack Weinberg <zack@codesourcery.com> - Chris Devers <cdevers@pobox.com> - Joseph S.
