I'm interested in helping stabilize vsha512*.

I saw vsha256* was stabilized in rust-lang/stdarch#1399. Is all that's needed a similar stabilization PR? (although possibly without the not(target_arch = "arm") gating since it's AArch64-specific anyway?)

[Amanieu]

Yes, just submit a stabilization PR and then we can start an FCP.

[tarcieri]

It looks like since it's autogenerated code, stabilizing vsha512* would involve stabilizing all of stdarch_neon_sha3 by modifying this line, which I can open a PR for: https://github.com/rust-lang/stdarch/blob/3961d3b/crates/stdarch-gen-arm/src/main.rs#L532
