Error with simd_wasm64 feature

[Titaniumtown]

I tried using this in my wasm project and I get the following error:

error[E0658]: use of unstable library feature 'simd_wasm64'

Odd. What version of rust are you using? I'm using 1.62.0.

What target are you using? I only tested with wasm32-unknown-unknown. Are you using the tier 3 wasm64-unknown-unknown target?

[Titaniumtown]

cargo build --release --target wasm32-unknown-unknown I am compiling for wasm32, and I'm using the latest nightly build as I need those features.

[Craig-Macomber]

I have no idea why calling core::arch::wasm::memory_grow claims to need #![feature(simd_wasm64)]. I'm on stable (and thus can even use such features) and it works fine.

Looks like core::arch::wasm is documented as marked with needing simd_wasm64: https://doc.rust-lang.org/core/arch/wasm/index.html

Maybe this is a recent regression on nightly?

[Craig-Macomber]

I have published a new version that should work around this issue.

[Craig-Macomber]

Looks like core::arch::wasm::memory_grow working at on on stable was a rustc bug, and its just an alias for core::arch::wasm32::memory_grow so my change is a good fix.

The readme is now more clear about just supporting wasm32 as well. I'm going to consider this resolved, but feel free to re-open if its not fixed for you in 0.1.2

Thanks!
