Comment on attachment 350444 [details] WIP View in context: https://bugs.webkit.org/attachment.cgi?id=350444&action=review > Tools/WebGPUShadingLanguageRI/Intrinsics.js:757 > + EPtr.box(!Number.isNaN(value.loadValue())); Nope. "normal" means both not nan and not denormalized > Tools/WebGPUShadingLanguageRI/Intrinsics.js:808 > + EPtr.box(castToFloat(bitwiseCast(Float32Array, Uint32Array, value.loadValue() & 0xFF))); We have to do more bit twiddling for this one. > Tools/WebGPUShadingLanguageRI/Intrinsics.js:815 > + EPtr.box(bitwiseCast(Uint32Array, Float32Array, castToHalf(value.loadValue())) & 0xFF); Ditto |
