mlir fails to build with Python 3.13.0a1. This report is automated and not very verbose, but we'll try to get back here with details.

You can follow these instructions to test locally in mock if your package builds with Python 3.13: https://copr.fedorainfracloud.org/coprs/g/python/python3.13/ Let us know here if you have any questions. Python 3.13 is planned to be included in Fedora 41. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.13. A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon. We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.

The syntax warnings have already been fixed upstream in LLVM 18 with commit e919a83f96fe016378926855cb79f9b86102f6e4.
This bug appears to have been reported against 'rawhide' during the Fedora Linux 40 development cycle. Changing version to 40.
