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?
