--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
That is, I'm talking about

      /* If there is call on a hot path through the loop, then
         there is most probably not much to optimize.  */
      else if (size.num_non_pure_calls_on_hot_path)
        {
          if (dump_file && (dump_flags & TDF_DETAILS))
            fprintf (dump_file, "Not unrolling loop %d: "
                     "contains call and code would grow.\n",
                     loop->num);
          return false;
