I think this is wrong: OpTypeRuntimeArray requires Shader capability, but the triple makes this run for Kernel. @aadeshps-mcw can you please help me understand what are you trying to test here? If we change the triple to spirv-unknown-vulkan-compute, which would run for Shader, there is no OpTypeRuntimeArray, instead there is an OpConstant, which I assume comes from some optimization/pass. @Keenuts can you confirm?

I just checked, mem2reg is getting rid of the alloca, so no array after that.

I realize the mistake was on my part due to a misunderstanding of the test. I’ll address it and submit a new PR at the earliest.

I have updated it in #149522. Let me know if that works for you, otherwise I can just mark it as XFAIL in the PR, so you can address it later in a different PR.
