Hi!
On (at least some of these) tests and on some targets, GCC prints messages
like:
./cc1 -quiet -O3 -fopt-info-vec-optimized -mvis vect-ivdep-1.c
vect-ivdep-1.c:11:3: optimized: loop vectorized using 8 byte vectors
vect-ivdep-1.c:11:3: optimized: loop versioned for vectorization to enhance alignment
and the versioning for alignment message according to this PR makes those
tests FAIL. We just want to make sure in these testcases we don't version
for alias, so this patch just prunes the versioning for alignment
diagnostics.
Bootstrapped/regtested on x86_64-linux and i686-linux, does it work on SPARC
and ok for trunk in that case?

As mentioned in the PR, another testcase was missed, this patch modifies
that one too. Ok for trunk?

this is wrong: either move the dg-prune-output before the first
dg-optimized (preferably) or adjust the line number distances to account
for the additional line.
Ok with that fixed.
Thanks.
