--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Hmm, I've done
void b (int *p)
{
p = (int *)__builtin_assume_aligned(p, __BIGGEST_ALIGNMENT__);
int *q = p + 255;
for(; p < q; ++p, --q)
{
int t = *p;
*p = *q;
*q = t;
}
}
and on x86_64 the accesses are all vectorized as aligned. So what's not
supported is aligned load + permuting elements as { 3, 2, 1, 0 } (reversing
them). I can't seem to find a suitable target for dg-require-effective-target
here. There's the kitchen-sink vect_perm that sparc doesn't have so I
could use that I guess.
