target-feature=+atomics #126778Description
I tried to build an example project for wasm64-unknown-unknown with target-feature=+atomics, but the std failed to build due to
wasm32 arch.
I could get std to build by adding #![feature(simd_wasm64)] to https://github.com/rust-lang/rust/blob/master/library/std/src/lib.rs, and a few cfg checks to import the correct module.
I could work on a PR if that's the right approach.
