```
  int old_cost = rtx_cost (*imm, mode, COMPARE, 0, true);
  int new_cost = rtx_cost (new_imm, mode, COMPARE, 0, true);

  if (dump_file && (dump_flags & TDF_DETAILS))
    {
      fprintf (dump_file, ";; cmp: %s, old cst: ",
               GET_RTX_NAME (*code));
      print_rtl (dump_file, *imm);
      fprintf (dump_file, " new cst: ");
      print_rtl (dump_file, new_imm);
      fprintf (dump_file, "\n");
      fprintf (dump_file, ";; old cst cost: %d, new cst cost: %d\n",
               old_cost, new_cost);
    }
