There's no control flow nor scalarizing for vectors. I trust this will be a good enough default for the scalar form (on GPUs) though I suppose CPUs may prefer the old control flow form. I doubt any would prefer the old vector form, though.
alive2 seems to be happy with the transformation (for `half2`): https://alive2.llvm.org/ce/z/RZ8Dc4 Let me know what you think. https://github.com/llvm/llvm-project/pull/115699 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
