Bug#1102660: unblock: rustc/1.85.0+dfsg2-3



Package: release.debian.org
Severity: normal
X-Debbugs-Cc: rustc@packages.debian.org, debian-rust@lists.debian.org, debian@fabian.gruenbichler.email
Control: affects -1 + src:rustc
User: release.debian.org@packages.debian.org
Usertags: unblock

Please unblock package rustc

[ Reason ]

See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1095863#70 and
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1095862

This undoes the i686 baseline lowering in rustc compared to upstream.

[ Impact ]
rustc-compiled binaries on i686 might be miscompiled and have subtle broken
behaviour or crashes

[ Tests ]
this change aligns rustc on i686 with upstream's baseline. the testsuite of
rustc itself covers a lot of toolchain behaviour and had to previously be
patched to accomodate for the deviation (see debdiff)

[ Risks ]
there will be a few crates that need changes to remove patches adapting to the
deviating previous baseline. in particular quite a lot of tests will fail if
they rely on certain properties of FPU behaviour.

[ Checklist ]
  [x] all changes are documented in the d/changelog
  [x] I reviewed all changes and I approve them
  [x] attach debdiff against the package in testing
