--- Comment #14 from Martin Sebor <msebor at gcc dot gnu.org> ---
Richard, thank you for the patch. It resolves the regression in the quality of
the code generated for the test on ppc64 (I am yet to test other ppc variants).
Unfortunately, while working on an improved test for the vectorization I
uncovered another regression in this area that manifests itself when the
destination address (as opposed to the source address) is not aligned as
expected. I posted the enhanced test to the list:
