The existence of convergence operations means you > have a convergent language and must optimize to known-not-convergent In languages like OpenCL and HLSL, this requirement is actually fine and we don't need it explicitly annotated. OpenCL and HLSL are effectively single-source kernel languages and all code gets inlined. So we can do robust attribute propagation. https://github.com/llvm/llvm-project/pull/80680 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
