--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The other thing is if lim/pre could figure out:
  _9 = hex.ptr;
  _11 = (sizetype) i_148;
  _12 = _9 + _11;
  _13 = _8 + 48;
  *_12 = _13;

The store at _12 does not have an effect on the value of hex.ptr. Then this
might be optimized away too.
