lower spirv ray query type to opaque debug type

[ChristianReinbold]

Pull request for Issue #7033. It is still lacking a test though. If you can give me a quick pointer to a test directory where I can reformulate my reproducer as a test, I will add it as well.

Thanks for contributing. This is a big help. The change look go to me.

You can add a test to https://github.com/microsoft/DirectXShaderCompiler/tree/20950d662f4d24850d7edfe1e647f6749d5c13b3/tools/clang/test/CodeGenSPIRV.

You can see examples in that directory. You'll want to add your hlsl source file with a RUN line at the top, and at least one CHECK line to look for code you expect to see.

You can run the tests by running:

ninja check-clang-codegenspirv

I am not building with ninja right now, but have a visual studio solution. Right now I am trying to launch tests via:

hcttest file-check "src\tools\clang\test\CodeGenSPIRV\attribute.location.lib.hlsl"

but it fails at the disassembly stage due to an invalid bitcode signature. Note that the compilation process seems to succeed. Whatever I am trying to do in order to make tests work, I seem to be completely on the wrong track here. That blocks me right now. No idea where to continue the investigation.

Sorry, I did not get back to you. Can run the tests by building the check-clang-codegenspirv target. Look for that target in visual studio.
