Description Alec Ari 2017-05-02 00:12:36 UTC

Hi everyone, I was just building Firefox and experimenting with -Ofast and realized that it was using -O2.

/etc/portage/env/nopie_opt.conf:

CFLAGS="-march=core2 -Ofast -fPIC -fstack-protector-strong -fomit-frame-pointer -pipe -g0 -s -msse -msse2 -msse3 -mssse3 -mmmx -mfpmath=sse"

CXXFLAGS="-march=core2 -Ofast -fPIC -fstack-protector-strong -fomit-frame-pointer -pipe -g0 -s -msse -msse2 -msse3 -mssse3 -mmmx -mfpmath=sse"

LDFLAGS="-march=core2 -Ofast -fPIC -fstack-protector-strong -fomit-frame-pointer -pipe -g0 -s -msse -msse2 -mssse3 -mmmx -mfpmath=sse -Wl,-z,now -Wl,-z,relro"

/etc/portage/package.env:

www-client/firefox nopie_opt.conf

grep "Ofast" /var/tmp/portage/www-client/firefox-45.8.0/temp/build.log returns no results, however -O2 shows up all over the place during the build.

If you feel I have closed your bug and it is still a current issue, please reopen and update it completely. We will not work bugs that have no ebuild in tree any longer or can not be reproduced with a current system.
