Thanks for the review. The motivation is mostly that the `simd` extensions in C++26 specify the `popcount` and `find_[first|last]_set` functions on a mask, which is a vector of bools https://en.cppreference.com/w/cpp/experimental/simd.html. The 'generic' bit counting functions are intended to be type generic and boolean vectors are 'bit-castable' to integers. I figured the most straightforward way to implement this was to extend the generic versions, but we could make new builtins if needed. https://github.com/llvm/llvm-project/pull/154203 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
