* 8503 wgsl depth texture (#8645)Sami Kiminki (NVIDIA)2025-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add built-in type aliases for DepthTexture* and unify Sampler*Shadow Add the following type aliases: - DepthTexture1D, DepthTexture1DArray - DepthTexture2D, DepthTexture2DArray - DepthTexture2DMS, DepthTexture2DMSArray - DepthTexture3D - DepthTextureCube, DepthTextureCubeArray These match with the type aliases for non-depth textures. Also, unify the Sampler*Shadow type aliases with DepthTexture* ones. This adds the following: - Sampler2DMSShadow - Sampler2DMSArrayShadow and removes the Sampler3DArrayShadow type alias. As a side-effect, the descriptions of Sampler*ArrayShadow type aliases are fixed ("texture-sampler for shadow" ==> "texture-sampler array for shadow"). Update the slang tests to use the newly introduced type aliases instead of the custom type aliases that use _Texture<> directly. Add DepthTexture testing in hlsl-intrinsic/texture/texture-intrinsics. Do this by extracting the test logic of computeMain() in a separate function and parametrize it for non-depth/depth texture types. This adds basic coverage for the following types: - DepthTexture1D - DepthTexture2D - DepthTexture3D - DepthTextureCube - DepthTexture1DArray - DepthTexture2DArray - DepthTextureCubeArray Issue #6166 Issue #8503
