SPV_REFLECT_RESULT_ERROR_SPIRV_INVALID_ID_REFERENCE with Slang + RTX Neural Shaders

[volt176]

I’m using the Slang compiler with RTX Neural Shaders (rtxns) to generate SPIR-V compute shaders. The SPIR-V runs correctly in Vulkan, but reflection via SPIRV-Reflect fails with: SPV_REFLECT_RESULT_ERROR_SPIRV_INVALID_ID_REFERENCE

The error is returned inside SPIRV-Reflect from ParseTypes(), which is invoked internally by spvReflectCreateShaderModule:

if (result == SPV_REFLECT_RESULT_SUCCESS) {
    result = ParseTypes(&parser, p_module);
    SPV_REFLECT_ASSERT(result == SPV_REFLECT_RESULT_SUCCESS);
}

Here is the SPIR-V file (renamed as a .txt) for testing:
Training.txt

The source code for the shader can be found here: RTXNS ShaderTraining sample

@volt176 thanks for the SPIR-V, was able to quickly detect it from lack of OpTypeCooperativeVectorNV being added, I have a PR up, confirmed it ran with this SPIR-V now
