URL: https://github.com/llvm/llvm-project/commit/f34483838937b1a01ee11ee22bdd6e13c81e9fff DIFF: https://github.com/llvm/llvm-project/commit/f34483838937b1a01ee11ee22bdd6e13c81e9fff.diff LOG: [clang-format] Keep the space between `not` and a unary operator (#135035) Also keep the space between `not` and `::`. Based on the [documentation](https://releases.llvm.org/20.1.0/tools/clang/docs/ClangFormatStyleOptions.html#spaceafterlogicalnot), it can be argued that SpaceAfterLogicalNot doesn't cover the alternative operator `not`.
