Official builds on x86 are only built with SSE2, with higher SIMD levels only explicitly enabled selectively in various files. I would encourage the distro build maintainers to fix this on their end by not supplying AVX flags to the build. Acceleration for higher levels of SIMD is still used in Mozilla builds, but again, we only selectively enable that in various parts of the moz.build where it is actually safe and properly gated by CPU feature-level checks.

Sure, I assume -march=native (or similar) is used somewhere (and maybe some of the build hosts started exposing AVX and friends to the build VMs). But I failed to find where as the build scripts are non-standard and the build log is not helping (e.g. there is no build line for SkM44.cpp -- it's likely one of those Unified_cpp's). I hope Wolfgang knows better... -- You are receiving this mail because: You are the assignee for the bug.
