Ira Rosen posted a couple of vectorizer patches intended for 4.8:
As she is no longer able to contribute to GCC, she has asked
me to help push these upstream now that 4.8 is in stage 1.
We've been carrying those patches for a while in our Linaro GCC
builds for ARM, and they're showing significant improvements in
certain embedded test cases.
I've now retested both patches on i386-linux with no regressions;
the PowerPC team has helped with retesting on powerpc64-linux
with no regressions, and there are (as expected) no significant
changes in PowerPC benchmark results either.
OK to commit the two patches to mainline?
