--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note LIM2 has way different IR selection which is kinda interesting since there
are no stores that happened in the bbs that were removed:
  if (_2 != 0)
    goto <bb 4>; [75.00%]
  else
    goto <bb 5>; [25.00%]

  <bb 4> [local count: 6515660663]:
  iftmp.8_23 = s.5_14 + -3;

  <bb 5> [local count: 8687547565]:
  # iftmp.8_24 = PHI <s.5_14(3), iftmp.8_23(4)>
