Yeah, I agree with you. But can be cases when someone in some narrow case needs to program logic by hand. Why restrict it? I also think that a generic interface is much better than achieving the same logic through builtins/intrinsics. https://github.com/llvm/llvm-project/pull/75182 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
