--- Comment #5 from avieira at gcc dot gnu.org ---
Not quite sure the third case has anything to do with epilogue vectorization
though... It still manifests itself with it turned off. Seems to be a lack of
"folding" again.

I think it would be useful to split testcases 2 and 3 into two new PR's as they
are unrelated issues to 1.
