Don't check for misaligned raw pointer derefs inside Rvalue::AddressOf From https://github.com/rust-lang/rust/pull/112026#issuecomment-1565686697: rustc 1.70 (stable next week) added a Mir pass to add pointer alignment checks in debug mode. Adding these checks caused some crates to break, but that was expected, since they contain broken code (https://github.com/rust-lang/rust/issues/111487) for tracking that. However, the checks added are slightly more aggressive than they should have been. Specifically, they also check the place in an `addr_of!` expression. Whether lack of alignment there is or isn't UB is unclear. This PR modifies the pass to not affect those cases. I spot checked the crater regressions and the ones I saw were not the case that this PR is modifying. It still seems good to not land anything overaggressive though |
