--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The problem is actually related to the front-end producing _Bool types:
  _Bool D.1714;
  _Bool D.1710;

<bb 2>:
  D.1714_3 = f1_1(D) < f2_2(D);
  D.1710_4 = D.1714_3;

*.original for 4.7:
  if (f1 < f2) (void) 0;

vs 4.8:
  (void) (f1 < f2);
