Sounds good. For info, the "new" MSVC preprocessor gives `0 23 1` (https://godbolt.org/z/Go6P4xq4a). With respect to the relative positioning for `2` and `3`, we have a situation where all implementations behave one way and the wording implies another. https://github.com/llvm/llvm-project/pull/162662 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
