--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
  <bb 3> [local count: 375809640]:
  _3 = g1;
  goto <bb 5>; [100.00%]

  <bb 4> [local count: 697932184]:
  g2.1_2 = g2;
  arr[0] = g2.1_2;
  _8 = g1;

  <bb 5> [local count: 1073741824]:
  # _6 = PHI <_8(4), _3(3)>

Which does not optimize unless using -O2.

This is on purpose.
