* rtl.h (simplify_replace_fn_rtx): Declare. (wrap_constant, unwrap_constant): Delete. * cfgexpand.c (unwrap_constant, wrap_constant): Delete. (expand_debug_expr): Don't call wrap_constant. * combine.c (rtx_subst_pair): Only define for AUTO_INC_DEC. (auto_adjust_pair): Fold into... (propagate_for_debug_subst): ...here. Only define for AUTO_INC_DEC. Just return a new value. (propagate_for_debug): Use simplify_replace_fn_rtx for AUTO_INC_DEC, otherwise use simplify_replace_rtx. * cselib.c (wrap_constant): Reinstate old definition. (cselib_expand_value_rtx_1): Don't wrap constants. * gcse.c (try_replace_reg): Don't use copy_rtx in the call to simplify_replace_rtx. (bypass_block): Fix formatting in calls to simplify_replace_rtx. * reload1.c (reload): Skip all uses for an insn before adjusting it. Use simplify_replace_rtx. * simplify-rtx.c (simplify_replace_fn_rtx): New function, adapted from... (simplify_replace_rtx): ...here. Turn into a wrapper for simplify_replace_fn_rtx. (simplify_unary_operation): Don't unwrap CONSTs. * var-tracking.c (check_wrap_constant): Delete. (vt_expand_loc_callback): Don't call it. (vt_expand_loc): Likewise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@153037 138bc75d-0d04-0410-961f-82ee72b054a4
