I think the internal option is less important to the clang users than the functionality enabled by the library. https://github.com/llvm/llvm-project/pull/211949 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
