If you let that get to the spirv backend it falls over with `Intrinsic selection not implemented` but you can have IR with the right amdgpu intrinsics in it. https://github.com/llvm/llvm-project/pull/131164 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
