Looks like as of 2 weeks ago the unsafe block should no longer be required: https://github.com/rust-lang/stdarch/pull/1714 https://github.com/rust-lang/stdarch/pull/1714 ..at least outside of loads/stores. From a bit of looking at the code though it seems like a good amount of those should be doable in a safe way with some abstractions.
