There was a problem hiding this comment.
Drive-by so I don't keep accidentally changing the output of issue-87707.run.stderr because my environment has RUST_BACKTRACE=full by default.

We were using the trait-ref substs instead of impl substs in
rustc_on_unimplemented, even when computing therustc_on_unimplementedattached to an impl block. Let's not do that.This PR also untangles impl and trait def-ids in the logic in
on_unimplementeda bit.Fixes #94675
