HasFallback only applies to the two-argument form. ------------ I don't have a strong opinion about the names. The whole "fallback behavior" thing was written back in the early days of clang, before we even had ubsan. I doubt we would handle that the same way today... and I don't think we need to carry it forward to new variants. If the user cares, they can explicitly request `__builtin_elementwise_ctz(x, 32)` or whatever. https://github.com/llvm/llvm-project/pull/131995 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
