--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
Yes.  Note we're simply vectorizing more and that puts more IL and in
particular more loops (prologue,epilogue,versions) down the pipeline.  Noth=
ing
we can do much about apart from making unrelated passes faster.

Unfortunately the extra vectorization doesn't result in a speedup in the end
(it's not to hot code regions).=
