Description doodydexter 2019-01-10 09:22:03 UTC

what's the status of PGO enabled builds? 

i've had success with this ebuild using clang 7.0.1: https://github.com/perfect7gentleman/pg_overlay/blob/master/www-client/firefox/firefox-64.0.ebuild


Installed versions:  64.0^d{tbz2}[?](10:04:12 AM 01/08/2019)(clang dbus eme-free jit lto pgo pulseaudio screenshot startup-notification system-harfbuzz system-icu system-jpeg system-libevent system-libvpx -bindist -custom-cflags -custom-optimization -debug -geckodriver -gmp-autoupdate -hardened -hwaccel -jack -kde -neon -selinux -system-sqlite -test -wifi L10N="-ru")

Seems this got enabled again with 65.0's ebuild.

But, correct me if I'm wrong, does it really still need xvfb? (currently enforced on xorg-server through virtualx)

I've been building clang+lto+pgo for some time now and I didn't have it. Firefox has a real headless mode now, it shouldn't need xvfb anymore to do profiling.

Like said, USE=pgo is available for since 2019.

Up to my knowledge, it is: If you would run in headless mode, you wouldn't optimize GUI parts.
