B) bump the i386 baseline in Debian to require SSE2, and stop disabling SSE2
there in rustc
C) disable all optimizations for Rust code on i386 (not really an option I
think, just here for completeness sake)
D) follow the other teams and stop building Rust on i386.
I am not personally invested in i386 at all, but that is still not a call that
I'd want to make as toolchain maintainer. If the release team prefers it over
B) and over risking running into the miscompilation issues in practice, then I
won't object.
FWIW, my (personal!) current preference would be B), followed by either
documenting the issue and accepting it or D). Given the far-reaching
implications of both B and D, I don't think this is a decision that either I or
the Rust team can make alone.
+1 for B). I would be happy to do the same (enable ss2 extensions) for
llvm too.
