--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Hmm,
 For ILP32 the only thing we have left is:
  milliDiff_6 = -milliDiff_5(D);
  minutesDiff_13 = milliDiff_6 / 60000;
  minutesDiff_8 = -minutesDiff_13;

For LP64:
  milliDiff_8 = -milliDiff_7(D);
  _3 = milliDiff_8 / 1000;
  _12 = (int) _3;
  minutesDiff_13 = _12 / 60;
  minutesDiff_10 = -minutesDiff_13;
...
  _17 = milliDiff_7(D) / 1000;
  _5 = (int) _17;
  minutesDiff_16 = _5 / 60;
