* fwprop.c (try_fwprop_subst): Use validate_unshare_change.
* postreload.c (reload_cse_simplify_set): Instead of copying the rtx early use validate_unshare_change. (reload_combine): Likewise. * recog.c (change_t): New field unshare. (validate_change_1): Rename from validate_change; add argument unshare. (validate_change): Turn into wrapper of validate_change_1; update prototype for bools. (validate_unshare_change): New. (confirm_change_group): Unshare changes if asked for; avoid unnecesary calls of df_insn_rescan. * recog.h (validate_change): Replace ints by bools. (validate_unshare_change): Declare. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@126050 138bc75d-0d04-0410-961f-82ee72b054a4
