As a part of the big MIR docs PR, I had added a comment indicating that
Rvalue::ShallowInitBox
is disallowed after drop elaboration, but this is not true (no idea why I thought it was). Codegen has support for it, and trying to enforce this rule in the validator causes compiling core to ICE on the very firstbox
statement.That being said, this
Rvalue
probably should be banned after drop elaboration - it doesn't seem like it's still useful for much. However, I do not have time right now to actually go investigate how difficult a change that is to make, so in the meantime fixing the docs to reflect the current situation seems like the right step.r? rust-lang/mir-opt
