I was thinking about `offsetof` being defined in some header, not in the intended system one. And then we [transitively] include "\_\_stddef_offsetof.h". Does it mean that in this case "\_\_stddef_offsetof.h" is processed only when building module "_Builtin_stddef"? https://github.com/llvm/llvm-project/pull/84127 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
