Building firefox (esr) with clang (13) and USE "pgo" Xvfb is started as user portage. But no -fprofile CFLAGS/CXXFLAGS are attempted to use and no profiling steps are taken, its just like normal build (without "pgo) --------- www-client/firefox-91.4.0::gentoo was built with the following: USE="clang dbus eme-free gmp-autoupdate hwaccel openh264 pgo pulseaudio system-harfbuzz system-jpeg -debug -geckodriver -hardened -jack -lto -screencast (-selinux) -sndio -system-av1 -system-icu -system-libevent -system-libvpx -system-webp -wayland -wifi" ABI_X86="(64)" L10N="ru -ach -af -an -ar -ast -az -be -bg -bn -br -bs -ca -ca-valencia -cak -cs -cy -da -de -dsb -el -en-CA -en-GB -eo -es-AR -es-CL -es-ES -es-MX -et -eu -fa -ff -fi -fr -fy -ga -gd -gl -gn -gu -he -hi -hr -hsb -hu -hy -ia -id -is -it -ja -ka -kab -kk -km -kn -ko -lij -lt -lv -mk -mr -ms -my -nb -ne -nl -nn -oc -pa -pl -pt-BR -pt-PT -rm -ro -sco -si -sk -sl -son -sq -sr -sv -szl -ta -te -th -tl -tr -trs -uk -ur -uz -vi -xh -zh-CN -zh-TW" CFLAGS="-fomit-frame-pointer -march=znver1 -mmmx -mno-3dnow -msse -msse2 -msse3 -mssse3 -mcx16 -msahf -mmovbe -maes -msha -mpclmul -mpopcnt -mfma -mbmi -mbmi2 -mavx -mavx2 -msse4.2 -msse4.1 -mlzcnt -mrdrnd -mf16c -mfsgsbase -mrdseed -mprfchw -madx -mfxsr -mxsave -mxsaveopt -mclflushopt -mxsavec -mxsaves -mmwaitx -mclzero -mtune=znver1 -pipe" CXXFLAGS="-fomit-frame-pointer -march=znver1 -mmmx -mno-3dnow -msse -msse2 -msse3 -mssse3 -mcx16 -msahf -mmovbe -maes -msha -mpclmul -mpopcnt -mfma -mbmi -mbmi2 -mavx -mavx2 -msse4.2 -msse4.1 -mlzcnt -mrdrnd -mf16c -mfsgsbase -mrdseed -mprfchw -madx -mfxsr -mxsave -mxsaveopt -mclflushopt -mxsavec -mxsaves -mmwaitx -mclzero -mtune=znver1 -pipe" FEATURES="assume-digests binpkg-docompress binpkg-dostrip binpkg-logs buildpkg cgroup config-protect-if-modified distlocks ebuild-locks fakeroot fixlafiles ipc-sandbox merge-sync multilib-strict network-sandbox news nodoc noinfo pid-sandbox preserve-libs protect-owned qa-unresolved-soname-deps sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync xattr" LDFLAGS="-s -Wl,--compress-debug-sections=zlib -Wl,-rpath=/usr/lib64/firefox,--enable-new-dtags" Reproducible: Always

Nice catch. We only activate PGO when you also set USE=lto (https://gitweb.gentoo.org/repo/gentoo.git/tree/www-client/firefox/firefox-95.0.ebuild?id=9f7c4921012897868c8f254d9a042b51de43e120#n798). That's because USE=pgo is a waste of time when running on code which wasn't inlined. We somehow lost > REQUIRED_USE="pgo? ( lto )" between 80.0.1-r1 and 81.0.
