I'm seeing vectori
The invoke.texi is correct. -ftree-vectorize is now simply a
short-hand to enable both loop and slp vectorizer. I will fix the the
help message appropriately.

I see. It would be also nice to fix -O3 entry in doc/invoke.texi that
currently reads:
--cut here--
@item -O3
@opindex
It is a bug in the help message dump. You can see that
ftree-loop-vectorize ftree-slp-vectorize are indeed enabled.

Hello!
4.9 does not enable -ftree-vectorize for -O3 (and Ofast) anymore. Is
this intentional?
$/ssd/uros/gcc-build/gcc/xgcc -B /ssd/uros/gcc-build/gcc -O3 -Q

This is the reason for low scores on SciMark v2.0 as conducted
