(In reply to Kimmo Kinnunen from comment #2) > What does it do? Attaching [AllowShared] annotations to WebGL types to align them to the spec. This [AllowShared] annotation allows these WebGL functions to accept ArrayBuffer / ArrayBufferView created from SharedArrayBuffer. By default, non-allow-shared ArrayBuffer etc. is rejected and throws TypeError. But when [AllowShared] annotation is attached, IDL can accept them.

We found that this is used in apps using wasm-threads and WebGL. https://twitter.com/Constellation/status/1371507429683302403

Thanks, had missed the feature. Looks good to me. We don't have the tests for these, I'm in process of importing new set of tests from WebGL conformance test suite that should then add some test coverage.

Thanks! The added test LayoutTests/webgl/webgl-allow-shared.html covers it too :)
