Until it is moved, it would be great if this was not at the very beginning of the header. The main readers of this file are the users of these APIs.

The naming issue I raised is not solved yet. https://github.com/llvm/llvm-project/pull/202372 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
