Btw, technically we only need to comment-out the f64 definitions here, since f32 seem to work correctly (which is why I haven't caught any invalid operations over #527) - but I've commented out both, because:

By the way, @Amanieu would you mind releasing the next version of compiler-builtins? I'd bump it in rustc straight away 🙂 |
