--- Comment #4 from Tibor Győri <tiborgyri at gmail dot com> ---
It might even be the case that the current cost model is correct, vectorization
is indeed sometimes unprofitable.
But in that case, the issue is how this is communicated to the user, the
"unsupported outerloop form" message does not feel informative enough. I mean
it is a trivial loop that will get completely unrolled, right? So in my mind
that already counts as "supported", but GCC is telling me it is not.
