--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
As for the other testcase:
  y_3 =3D x_2(D) & -4294967296;
  z_4 =3D (intD.9) x_2(D);
  _1 =3D (long intD.12) z_4;
  _5 =3D _1 | y_3;

If we could optimize:
  z_4 =3D (intD.9) x_2(D);
  _1 =3D (long intD.12) z_4;

Into:
_1 =3D x_2(D) & 4294967295;

It would just work.=
