--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The broken IR has been there since at least 4.9.0:
  <bb 2>:
  _1 =3D x_4(D) > 41;
  baz (x_4(D), y_5(D));
  goto <bb 4>;

  <bb 3>:
  ABNORMAL_DISPATCHER (0);

  <bb 4>:
  _8 =3D y_5(D) !=3D 0;
  _9 =3D x_4(D) =3D=3D 42;
  _11 =3D x_4(D) > 42;
  _12 =3D _1 | _8;
  _13 =3D (int) _12;


4.7.x didn't have the ABNORMAL_DISPATCHER part of the IR either.=
