4090 build != host sysrooted builds.
4091 * configure.in (SYSTEM_HEADER_DIR): Make sure it contains
4092 TARGET_SYSTEM_ROOT even on sysrooted natives.
4093 * configure: Rebuilt.
4095 2003-04-10 Zack Weinberg <zack@codesourcery.com>
4097 * c-decl.c (struct binding_level): Add shadowed_tags and
4098 function_body; remove this_block, tag_transparent, and
4099 subblocks_tag_transparent; update comments.
4100 (clear_binding_level, lookup_tag_reverse): Kill.
4101 (make_binding_level): Use ggc_alloc_cleared or memset.
4102 (lookup_tag): Remove struct binding_level* parameter. All
4103 callers changed. Just look at IDENTIFIER_TAG_VALUE, and
4104 current_binding_level->tags if asked for thislevel_only or if
4105 we might have to diagnose "struct foo; union foo;"
4106 (pushlevel): Ignore argument. Do not push another binding
4107 level on the transition from the parameters to the top level
4108 of the function body; just tweak the flags and proceed.
4109 (poplevel): Overhaul. Clear IDENTIFIER_TAG_VALUEs; on exiting
4110 a function body, separate the parameter list from the
4111 top-level local variables.
4112 (set_block): Do nothing.
4113 (pushtag): Set IDENTIFIER_TAG_VALUE and add an entry to
4114 shadowed_tags if necessary.
4115 (warn_if_shadowing): Nuke the special case for local shadowing
4117 (pushdecl): Do not create a shadow entry if we are replacing
4118 an older decl in the same binding level.
4119 (pushdecl_function_level): Tweak for new way of indicating
4121 (shadow_tag_warned): Use TYPE_NAME, not lookup_tag_reverse.
4122 (start_function): Don't set subblocks_tag_transparent.
4123 (finish_function): Fix up the binding_level stack for totally
4124 empty functions. Otherwise, don't call poplevel.
4126 * c-common.c (shadow_warning): MANDATORY argument is no longer
4127 necessary. Always use plain warning.
4128 * c-common.h: Update to match.
4130 * cfglayout.c (scope_to_insns_initialize): Clear block when we
4131 hit the FUNCTION_DECL.
4132 * function.c: Do not create cyclic tree structure.

4155 (clone_underlying type): Split out of pushdecl.
4156 (c_print_identifier): Update to match changes to struct
4158 (poplevel): Delete #if 0 block. Make externals invisible
4159 instead of clearing their IDENTIFIER_SYMBOL_VALUEs. Don't
4160 call clear_limbo_values. Refer to IDENTIFIER_SYMBOL_VALUE not
4161 IDENTIFIER_GLOBAL_VALUE or IDENTIFIER_LOCAL_VALUE.
4162 (duplicate-decls): For real parm decl after a forward decl,
4163 set TREE_ASM_WRITTEN here. Allow void foo(...) followed by
4164 foo(...) { } with only a warning. Say whether a previous
4165 declaration was implicit.
4166 (warn_if_shadowing): Now handles all shadowing, not just
4167 local-over-local. Clarify comments.
4168 (pushdecl): Rewritten. There is no longer a distinction
4169 between global and local symbol values; they're all
4170 IDENTIFIER_SYMBOL_VALUE. Call record_external_decl on all
4171 DECL_EXTERNAL decls, and use any_external_decl to check
4172 against previous externals. Kill #if 0 blocks. Don't
4173 tolerate error_mark_node being NULL.
4174 (pushdecl_top_level): Handle only those cases which
4175 Objective C (the only user) needs.
4176 (pushdecl_function_level): New function.
4177 (implicitly_declare): Create ordinary decls with
4178 C_DECL_IMPLICIT set. Recycle old decls, however they got
4180 (lookup_name): It's always IDENTIFIER_SYMBOL_VALUE. Return 0
4181 for C_DECL_INVISIBLE symbols.

4187 Use C_DECL_ISNT_PROTOTYPE and C_DECL_IMPLICIT.
4188 (store_parm_decls): It's IDENTIFIER_SYMBOL_VALUE now.
4189 (identifier_global_value): Same. Must scan
4190 global_binding_level in extremis.
4192 * c-typeck.c (undeclared_variable): New static function, split
4193 from build_external_ref.
4194 (build_external_ref): Use DECL_CONTEXT, not
4195 IDENTIFIER_LOCAL_VALUE, to decide whether a local hides
4196 an instance variable. Restructure for clarity.
4197 * objc/objc-act.c: Use identifier_global_value, not
4198 IDENTIFIER_GLOBAL_VALUE.
