--- Comment #13 from rsandifo at gcc dot gnu.org <rsandifo at gcc dot gnu.org> 
---
The patch is no longer effective after
g:96146e61cd7aee62c21c2845916ec42152918ab7, since e.g.:

int
or_shift_u3a (unsigned i)
{
  i &= 7;
  return i | (i << 11);
}

now gets folded to:

  i_2 = i_1(D) & 7;
  _5 = i_2 * 2049;

We then expand the multiplication as plus+shift rather
than ior+shift.
