Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Attachment #29355|0 |1 is obsolete| | --- Comment #10 from Richard Biener <rguenth at gcc dot gnu.org> 2013-02-05 13:07:51 UTC --- Created attachment 29356 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29356 patch This is what I am testing now. Of course nothing tells us (yet) if that fixes this bug - the slowdown of rnflow.f90 - which might be caused by us vectorizing this loop at all (as far as I understand before the change we did not vectorize it).
