[Pkg-rust-maintainers] Bug#908561: i386 rustc produces SSE2 instructions

[Mike Hommey]

Package: rustc
Version: 1.28.0+dfsg1-2
Severity: critical

Build anything with the rustc compiler for i386, and the result will
contain SSE2 instructions. This means rust-based packages don't support
the full range of what the i386 Debian architecture supports.

Specifically, this is the main cause for #908396/#908449.
