Latest version (1.2.11) fails to detect SIMD (UMD version)

phsultan opened this issue 3 years ago · comments

Hi all,

It looks like the currently available version from UMD at https://unpkg.com/wasm-feature-detect/dist/umd/index.js fails to detect SIMD.

To reproduce

enable WebAssembly SIMD support for Chrome 90 (in chrome://flags)
go to https://unpkg.com/wasm-feature-detect/dist/umd/index.js (will redirect to https://unpkg.com/wasm-feature-detect@1.2.11/dist/umd/index.js))
copy/paste the output to the JS console
run wasmFeatureDetect.simd().then(res => { console.log(res); }) => logs false

The previous version at https://unpkg.com/wasm-feature-detect@1.2.10/dist/umd/index.js logs true as expected.

Let me know if I missed something, thanks for the great work!

This is sadly working as intended.

The SIMD proposal had op-code changes, and Chrome 90 only supports the old SIMD. Chrome 91 goes stable today and we fixed wasm-feature-detect for that. See #43.

Gonna close this, but feel free to re-open if there are any further issues on this.
