Matthias Krüger f1f7560598 Rollup merge of #105317 - RalfJung:retag-rework, r=oli-obk ... make retagging work even with 'unstable' places This is based on top of https://github.com/rust-lang/rust/pull/105301. Only the last two commits are new. While investigating https://github.com/rust-lang/unsafe-code-guidelines/issues/381 I realized that we would have caught this issue much earlier if the add_retag pass wouldn't bail out on assignments of the form `*ptr = ...`. So this PR changes our retag strategy: - When a new reference is created via `Rvalue::Ref` (or a raw ptr via `Rvalue::AddressOf`), we do the retagging as part of just executing that address-taking operation. - For everything else, we still insert retags -- these retags basically serve to ensure that references stored in local variables (and their fields) are always freshly tagged, so skipping this for assignments like `*ptr = ...` is less egregious. r? ```@oli-obk```		2022-12-08 12:57:30 +01:00
