--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
So we end up vectorizing the outer loop in
for (; a<6; a++)
{
b ^= e;
tem = d[a*6];
for (c = 0; c < 2; c++)
tem |= 9;
d[a*6] = tem;
}
where the store-motioned d[] load wasn't vectorizable before the change.
We generate totally stupid vectorized b ^= e and then fuck up trying to
generate totally stupid vectorized d :/
