currently falling back 2 more orthodox USE flags cancelling custom-cflags gmp-autoupdate lto pgo USE flags.
My advice: BACKUP your working firefox as binary package before upgrade achievement.
| Code: | | quickpkg --include-config y <ebuild-name> |
I always wished portage to be able to backup current installed package as binary via a on-the-fly activated feature of some sort,; unfortunately it doesn't.
Thks 4 ur attention.
EDIT: | Code: | | CPU_FLAGS_ARM="-neon" |
seems suspiscious.

71+lto+pgo+usual flags working fine for me but I'm using clang for firefox since it's what they primarily use upstream and test with (gcc support is more like an afterthought at this point), generally I'd recommend people to do the same unless they really want to avoid clang on their system.
Although if a combination of USE flags is known to be broken, it's also gentoo's problem.
Edit update: which is now fixed for 71.0 in gentoo (gcc+lto+pgo should work again)

will give clang USE flag a chance one currentl ebuilding finishes.
BTW do you have custome-cflags activated?

Well, ""technically"" I do, but I'm more aggressive and preventing flag stripping from working in the first place system-wide (at my own risks). That aside, gcc tend to be a lot more pedantic with some aggressive optimization and firefox doesn't always give proper compiler hints which can lead to this kind of segfaulty or unexpected behavior situation.
I also have RUSTFLAGS="-Ctarget-cpu=native -Copt-level=2" which I believe/hope helps a bit performance-wise, not that I'm overly familiar with rust optimizations. |

Hmm,
seems you never heard of the FEATURES variable in make.conf. There is a feature named "buildpkg". |

AFAIR this feature build a bin package of the currently building package, it doesn"t currentl y backup currently installed one.
Will double chack, as I may have misunderstood the feature in the first plcce. | Code: | -buildpkg [ y | n ], -b
Tells emerge to build binary packages for all ebuilds processed in addition to actually merging the packages. Useful for maintainers or if you administrate multiple Gentoo Linux systems (build once, emerge tbz2s everywhere) as well as disaster recovery. The package will be created in the PKGDIR directory (see make.conf(5)). An alternative for already-merged packages is to use quickpkg(1) which creates a tbz2 from the live filesystem. |

Just noticed there was a bug for this, thought it wasn't the same thing at first. "Fixed" in this commit by well, blocking pgo with gcc.
So yeah, if want to keep using pgo, for now guess have to use clang (or firefox-bin which supposedly uses clang+lto+pgo too, but you do miss on some hardware-specific optimizations, usage of more system libraries, and few options like native jack/alsa support). clang as I mentioned before is probably better given the low support/testing with gcc by mozilla which is what leads to those problems.
Edit: Correction, apparently the cause was lto. But pgo USE forces lto so you still can't use pgo. Won't be best performance but if just need it to "work" with gcc just disable lto.

I've seen it too, but quite early, and didn't weent deep into understanding from first post.
Thks 4 pointing out for the update.
This should ease next ebuild, likely to avoid the 'try and error' thingie here.
firefox-bin getting internet back again, but only as workaround: jack is required here.
My two cents this issue will soon be fixed upstream.

EDIT : Arghhh, =llvm-8  Need to rebuild that toolchain
Log snippet while building -clang | Code: | USE: abi_x86_64 amd64 cpu_flags_x86_avx2 custom-cflags elibc_glibc jack kernel_linux l10n_fr lto pgo startup-notification system-av1 system-harfbuzz system-icu system-jpeg system-libevent system-libvpx system-sqlite system-webp userland_GNU wayland
FEATURES: distcc-pump network-sandbox preserve-libs sandbox userpriv usersandbox
Unable to unshare: EINVAL
Will use LLVM slot 9! |
I hope having both clang/llm|8,9] installed here will not cause any trouble. |

Hm? You should be able to use any llvm from 6 to 9 for firefox (it has all of them in depends), I only have llvm-9 myself (that one isn't marked stable though).
Edit: and yes, you need lld
Edit2: and just emerge clang:8 if you don't want 9
All of those can coexist anyway that's why slots exist. |

Ok got it, I missed a few masked such as: | Code: | sys-devel/lld-9.0.0
sys-libs/compiler-rt-sanitizers-9.0.0 |
That's why portage was pulling clang:8 along with firefox[clang].

| Code: | | ld.lld: error: unknown argument '-fuse-ld=bfd' |
I don't think telling ld.lld to use ld.bfd is supposed to work out (it's in your LDFLAGS).
Edit: Generally there's no reason to even use this flag globally (only for exceptions if needed), you can use binutils-config to set a default but currently it's already ld.bfd looking at your --info so there's no need to touch this. Just cleanup the flag and let the ebuild pick the right thing.

| The ebuild already takes care of everything if you just have the clang USE flag, there's nothing to do except make sure you don't have flags that clang/lld can't use (as pointed above), but "most" flags work for both. |
