HLSL validation error when a Texture2D is inside a cbuffer #2754
Description
Here's a minimal example that triggers the error.
Do you think it's legit ? This code is accepted by fxc.exe.
// input.frag.hlsl (updated)
cbuffer MyCBuffer
{
Texture2D myTexture;
SamplerState mySampler;
}
float4 main(float4 parFragIn : SV_POSITION) : SV_TARGET
{
return myTexture.SampleLevel(mySampler, float2(0, 0), 0).rgba;
}
% glslangValidator -V100 --spirv-val -S frag -D --target-env vulkan1.0 input.frag.hlsl -e main
input.frag.hlsl
error: SPIRV-Tools Validation Errors
error: In Vulkan, OpTypeStruct must not contain an opaque type.
