I think leading/trailing are relatively common terms in math *for numerals*. But this patch is the first thing that extends them to vectors AFAICT, so we need to be careful about it. What's the use-case for vector clz/ctz? 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
