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. (In reply to Ionen Wolkens from comment #1) > But, correct me if I'm wrong, does it really still need xvfb?
