It would be nice to be able to handle uninitialized memory, like with the atomic-maybe-uninit crate. I'm not familiar enough with atomic instructions to know how this could be done.

Once rust-lang/rust#114790 or an alternative is merged, it would be easy to extend the inline assemblies used in portable-atomic to work with MaybeUninit as well. Once that happens, I may start to consider merging atomic-maybe-uninit into portable-atomic.

It looks like the PR mentioned above has been merged into Rust v1.74.
