--- Comment #10 from Richard Biener <rguenth at gcc dot gnu.org> ---
  # j_19 =3D PHI <_14(8), j_22(5)>
  _9 =3D j_19 !=3D 1;
  _14 =3D (long int) _9;

so the vectorizer interesting thing is whether we can handle (equality)
compares the same as other associative operations (apart from the
involved cast).  Now the above isn't canonical, j_19 ^ 1 was though.=
