I've actually toyed around with implementing time safe operations in rust. We have the advantage that few implementations of rust exist. So in contemporary rust I can just disable inlining and introduce a function call. Not something that's safe to do in c, as far as i know. Now the compiler guys will never vouch for this behavior but once you narrow your targets things get interesting with security. Intel and Arm are both interesting platforms with a lot of quirks!
