Well, for the sparc, it appears that it's only the sim which
cares about it.  From sparc_push_dummy_frame():

  if (strcmp (target_shortname, "sim") != 0)
    {
      write_fp (old_sp);

      /* Set return address register for the call dummy to the current PC.  */
      write_register (I7_REGNUM, read_pc () - 8);
    }
  else
    ...

I wonder why the sim was being special cased in the first place?
