--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
So even after the recent ifcombine work we still produce during early folding:
if (x.j != sK.j || ((BIT_FIELD_REF <x, 8, 0> ^ BIT_FIELD_REF <sK, 8, 0>) &
64) != 0)
{
abort ();
}
and ifcombine does not optimize this further.
Disabling optimize_bit_field_compare optimizes this fully even before
ifcombine has a chance to perform the same optimization.
