This passes for me, even in -m32 mode (if -msse is added, like vect.exp
does):
% ./cc1 -ftree-vectorize -fno-vect-cost-model -msse2 -O2 \
vect-114.c -ftree-vectorizer-verbose=2 2>&1 | grep note:
vect-114.c:13: note: LOOP VECTORIZED.
vect-114.c:6: note: vectorized 1 loops in function.

Please note. The failure is

For some reason, it only fails with 32bit gcc.

Whoops. Yeah, I only added x86_64-*-* to the vect_perm targets. Obviously,
as sse2 is active by default for the vectorizer testsuite I also need to
add the i?86-*-* targets. H.J., can you try with this patch on a native system
(so that we may see any possible fallout)?
