Did you test this with ClangIR enabled? `-DCLANG_ENABLE_CIR=True` Also, which header files are generated from those *.def files and are those affected? If yes, how?

The script should be included in the submission, perhaps as a comment. That's primarily to preserve the history and for downstream users that have made local modifications to those files.

I will try to take a closer look tomorrow.
