--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I have a patch which gets the optimized code (at least being able to generate
at the rtl level):
  _1 = p_3(D) & 1;
  _7 = _1 != 0;
  _6 = (unsigned int) _7;
  _9 = p_3(D) - _6;


        movl    %edi, %eax
        andl    $-2, %eax
        ret

The patch is the one for PR 103216.
