rust-lang/stdarch#1266 has landed and shipped in v1.59

Note that documentation still displays the intrinsics as unstable due to a rustdoc bug: rust-lang/stdarch#1268

It should be possible to remove the feature gate now and enable SIMD on ARM by default.

Thanks for the heads-up. Will look into it.

One thing to note though is that the neon target feature on which those intrinsics depend have not been stabilized yet but will be in 1.61

Fixed in v0.1.4. For Rust 1.59 and 1.60 the aarch64_neon feature is still required for the aarch64 SIMD implementation. For Rust 1.61 the aarch64 SIMD implementation is enabled automatically with availability of target_feature = "neon".
