`isHorizontalWhitespace` only matches `' '`, `'\t'`, `'\f'`, `'\v'`. I tried replacing the conditions by ```cpp *CurPtr == ' ' || *CurPtr == '\t' || *CurPtr == '\f' || *CurPtr == '\v' ``` but it is slower, which is understandable seeing [what it optimizes to](https://godbolt.org/z/P6coT8nn5). https://github.com/llvm/llvm-project/pull/180819 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
