Excellent! Thank you! Yay for being able to use the vanilla Rust CPU targeting config going forward. For clarification: Does this decision apply to 32-bit x86 Linux as well? (It would be sad to have to supply and maintain non-SSE2 x86 code paths just for Linux.)

Regardless of what the answer is to the question above about requiring SSE2 on Linux, it's safe to assume that the Linux updater, too, is going to need to filter on SSE2 availability at some point. -- Henri Sivonen hsivo...@hsivonen.fi https://hsivonen.fi/ _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
