Description
I am trying to implement the RWTexture2DMS feature from SM 6.7 using DXC packages from the Agility SDK.
This is a dummy shader with minimal code.
Surprisingly, the shader compiles fine for DXIL, https://godbolt.org/z/z8qvbMEjd
but fails with SPIR-V, https://godbolt.org/z/59nPrsbdo
Would this be fixed in the coming some weeks?

Research direction
Start by running the minimal shader examples in the linked Godbolt DXIL and SPIR-V reproductions and compare their results. Trace the SPIR-V backend path for RWTexture2DMS support, using the DXIL success as the expected behavior. Done means the dummy Shader Model 6.7 shader compiles successfully for SPIR-V.
