I am writing shaders for my appliaction in HLSL and using the DirectX shader compiler (DXC) to compile it to SPIR-V. However, if I want to emit additional reflection information, I need to use the -fspv-reflect flag, which implicitly requires VK_GOOGLE_user_type and VK_GOOGLE_hlsl_functionality1 device extensions. It seems like the latter, VK_GOOGLE_hlsl_functionality1 extension is not supported at all by NVIDIA drivers, according to the vulkan gpuinfo website.
It would be great if we could have support for this extension, in making development easier.
