/* Adjust the stack pointer by minus ADJUST (an rtx for a number of bytes).
   This pushes when ADJUST is positive.  ADJUST need not be constant.  */

void
anti_adjust_stack (rtx adjust)
{
  rtx temp;

  if (adjust == const0_rtx)
    return;

  /* We expect all variable sized adjustments to be multiple of
     PREFERRED_STACK_BOUNDARY.  */
  if (CONST_INT_P (adjust))
    stack_pointer_delta += INTVAL (adjust);

However, PREFERRED_STACK_BOUNDARY isn't fixed at this time.
