Using LLVM to target GPUs is one of those ideas that's a lot prettier on paper than it is in practice. There are so many problems… nonetheless, multiple vendors invested a lot in this approach and are stuck with it. At least trying to integrate DirectX and HLSL upstream might force LLVM to fix some of the GPU pain points? The fact there is no upstream SPIR-V backend after all these years doesn't give me much hope though.
