rtl.h (simplify_replace_fn_rtx): Declare.
gcc/
* 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.
