--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The bug I think is ifcvt:

  _ifc__30 = e[d.3_23];
  _ifc__37 = _24 ? 0 : _ifc__30;
  e[d.3_23] = _ifc__37;

It was a bug before r15-4397-g70f59d2a1c51bd but it didn't get exposed
beforehand in the instructions; even though it was there.
