--- Comment #13 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
VRP is rewriting:
  _75 =3D _33 ? -1 : 0;
to:
  _38 =3D (<signed-boolean:1>) _33;
  _75 =3D -_38;


Folding statement: _75 =3D _33 ? -1 : 0;
Applying pattern match.pd:3954, gimple-match.c:142059
gimple_simplified to _38 =3D (<signed-boolean:1>) _33;
_75 =3D -_38;
Folded into: _75 =3D -_38;
