Do we need to do this dance? I would have assumed this header would be (with a header guard): ``` #ifdef __STDC_DEFER_TS25755__ #define __STDC_VERSION_STDDEFER_H__ 202602L #define defer _Defer #endif ``` We don't want to redefine `__STDC_DEFER_TS25755__` to 2 because we're not providing `defer` as a keyword, only `_Defer`. And we don't need to worry about working with other implementations because this header is tied to Clang itself, so we don't need to worry about the value being `2` instead. https://github.com/llvm/llvm-project/pull/162848 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
