--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The tree level looks fine, though I didn't look at the aliasing info that is
exported:
  <bb 2> [local count: 1073741824]:
  MEM[(long int *)p4_2(D)] = 1;
  _6 = (long unsigned int) index1_3(D);
  _7 = _6 * 8;
  _8 = p4_2(D) + _7;
  *_8 = 2;
  _9 = (long unsigned int) index2_4(D);
  _10 = _9 * 8;
  _11 = p4_2(D) + _10;
  _12 = *_11;
  MEM[(long int *)_11] = _12;
  _5 = MEM[(long int *)p4_2(D)];
  return _5;
