--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
The log file shows the loop was already vectorized by loop vectorization.  How
did you configure gcc?  It might be you configured a default -march/tune that
doesn't match the testcase expectation (and the testcase could probably use
-ftree-slp-vectorize instead of -ftree-vectorize).
