Comment 7 Georgy Yakovlev archtester gentoo-dev 2020-06-04 05:32:12 UTC
sorry for ppc64 spam here, firefox is the only  browser on ppc64 working out-of-the-box and users reporting failures.

ebuild currently fail with clang completely because elf-hack is not supported, so condition that already skips arm64 needs to be extended to ppc64 as well, something like this

> if use clang && ! use arm64 && ! use ppc64; then


but even with this it fails to build with clang, I'll file a separate bug for this and track separately.
but it's kinda relevant tue to switch to use clang by default.

-march=skylake-avx512 fails, -march=skylake seems to work. You might consider downgrading -march= value as a workaround. Newer targets will always have a higher chance of hitting ICEs.
