901 * configure: Rebuilt.
903 2003-04-10 Zack Weinberg <zack@codesourcery.com>
905 * c-decl.c (struct binding_level): Add shadowed_tags and
906 function_body; remove this_block, tag_transparent, and
907 subblocks_tag_transparent; update comments.
908 (clear_binding_level, lookup_tag_reverse): Kill.
909 (make_binding_level): Use ggc_alloc_cleared or memset.
910 (lookup_tag): Remove struct binding_level* parameter. All
911 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
912 current_binding_level->tags if asked for thislevel_only or if
913 we might have to diagnose "struct foo; union foo;"
914 (pushlevel): Ignore argument. Do not push another binding
915 level on the transition from the parameters to the top level
916 of the function body; just tweak the flags and proceed.
917 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
918 a function body, separate the parameter list from the
919 top-level local variables.
920 (set_block): Do nothing.
921 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
922 shadowed_tags if necessary.
923 (warn_if_shadowing): Nuke the special case for local shadowing
924 parameter.
925 (pushdecl): Do not create a shadow entry if we are replacing
926 an older decl in the same binding level.
927 (pushdecl_function_level): Tweak for new way of indicating
928 function scope.
929 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
930 (start_function): Don't set subblocks_tag_transparent.
931 (finish_function): Fix up the binding_level stack for totally
932 empty functions. Otherwise, don't call poplevel.
934 * c-common.c (shadow_warning): MANDATORY argument is no longer
935 necessary. Always use plain warning.
936 * c-common.h: Update to match.
938 * cfglayout.c (scope_to_insns_initialize): Clear block when we
939 hit the FUNCTION_DECL.
940 * function.c: Do not create cyclic tree structure.
942 2003-04-10 Zack Weinberg <zack@codesourcery.com>
944 * c-tree.h (struct lang_identifier): Replace global_value,
945 local_value members with symbol_value, tag_value. Kill

962 (any_external_decl, record_external_decl): New static functions.
963 (clone_underlying type): Split out of pushdecl.
964 (c_print_identifier): Update to match changes to struct
965 lang_identifier.
966 (poplevel): Delete #if 0 block. Make externals invisible
967 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
968 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
969 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
970 (duplicate-decls): For real parm decl after a forward decl,
971 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
972 foo(...) { } with only a warning. Say whether a previous
973 declaration was implicit.
974 (warn_if_shadowing): Now handles all shadowing, not just
975 local-over-local. Clarify comments.
976 (pushdecl): Rewritten. There is no longer a distinction
977 between global and local symbol values; they're all
978 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
979 DECL_EXTERNAL decls, and use any_external_decl to check
980 against previous externals. Kill #if 0 blocks. Don't
981 tolerate error_mark_node being NULL.
982 (pushdecl_top_level): Handle only those cases which
983 Objective C (the only user) needs.
984 (pushdecl_function_level): New function.
985 (implicitly_declare): Create ordinary decls with
986 C_DECL_IMPLICIT set. Recycle old decls, however they got
987 created.
988 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
989 for C_DECL_INVISIBLE symbols.
990 (lookup_name_current_level): Likewise. Use chain_member.
991 (c_make_fname_decl): Don't muck with DECL_CONTEXT.
992 Use pushdecl_function_level.
993 (builtin_function): Use C_DECL_INVISIBLE.
994 (start_function): Don't muck with IDENTIFIER_IMPLICIT_DECL.
995 Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
996 (store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
997 (identifier_global_value): Same. Must scan
998 global_binding_level in extremis.
1000 * c-typeck.c (undeclared_variable): New static function, split
1001 from build_external_ref.
1002 (build_external_ref): Use DECL_CONTEXT, not
1003 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
1004 an instance variable. Restructure for clarity.
1005 * objc/objc-act.c: Use identifier_global_value, not
1006 IDENTIFIER_GLOBAL_VALUE.
