--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Related is optimizing:
  _1 = (long unsigned int) j_5(D);
  _2 = _1 * 4;
  t_7 = i_6(D) + _2;
  _3 = (long unsigned int) k_8(D);
  _4 = _3 * 4;
  t1_9 = i_6(D) + _4;
  _10 = MAX_EXPR <t_7, t1_9>;

into:
i_6(D) + MAX_EXPR <_2, _4>

The non ptr_plus case is filed as PR 116008.
