--- Comment #27 from Jiu Fu Guo <guojiufu at gcc dot gnu.org> ---
For -O2, since a few optimizations are not enabled (e.g. some loop-based
optimizations), the code was not optimized too much.
At -O3, now, GCC could vectorize it. While with GCC 4.8, the code was not
vectorized. I guess the pain in performance may be mitigated.
