Thanks, got it! I misunderstand before. [cpp.pre]/p4: At the start of phase 4 of translation, the [group](https://eel.is/c++draft/cpp.pre#nt:group) of a [pp-global-module-fragment](https://eel.is/c++draft/cpp.pre#nt:pp-global-module-fragment) shall contain neither a [text-line](https://eel.is/c++draft/cpp.pre#nt:text-line) nor a [pp-import](https://eel.is/c++draft/cpp.import#nt:pp-import)[.](https://eel.is/c++draft/cpp.pre#4.sentence-1).is/c++draft/cpp.pre#4.sentence-1) https://github.com/llvm/llvm-project/pull/164106 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
