On the `clspv` side, we only care about functions that we are not capable of translating with the correct precision using a few Vulkan SPIR-V operators. - rhadd: https://github.com/google/clspv/blob/fea65392ea282dec9a43c3ab86fb63b890f6354e/lib/ReplaceOpenCLBuiltinPass.cpp#L3691 - popcount: https://github.com/google/clspv/blob/fea65392ea282dec9a43c3ab86fb63b890f6354e/lib/SPIRVProducerPass.cpp#L4332 So what `clspv` relies on is math functions that are easy to translate with a maintainable number of Vulkan operators. https://github.com/llvm/llvm-project/pull/116786 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
