Provided Methods§

After a stack frame got pushed, retag the return place so that we are sure it does not alias with anything.

This is a HACK because there is nothing in MIR that would make the retag explicit. Also see https://github.com/rust-lang/rust/issues/71117.

Mark the given tag as exposed. It was found on a pointer with the given AllocId.
