--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
We start out with:
  (*A.1_23)[i_33]{lb: 0 sz: _10 * 4}[j_34]{lb: 0 sz: _11 * 4}.b{off: _13 * 4} =
2;

And then we add:
  _ifc__49 = (*A.1_23)[i_33]{lb: 0 sz: _10 * 4}[j_34]{lb: 0 sz: _11 *
4}.D.2748{off: ((sizetype) SAVE_EXPR <n.0> + 3 & 18446744073709551612) + 4};
