* gimplify.c (gimplify_type_sizes): When not optimizing, ensure TYPE_MIN_VALUE and TYPE_MAX_VALUE is not is not DECL_IGNORED_P VAR_DECL. * cfgexpand.c (expand_used_vars): Keep DECL_ARTIFICIAL !DECL_IGNORED_P vars in local_decls list for instantiate_decls, ggc_free other TREE_LIST nodes from that chain. * function.c (instantiate_decls): Instantiate also DECL_RTL of vars in cfun->local_decls, free that list afterwards. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@140459 138bc75d-0d04-0410-961f-82ee72b054a4
