It would be nice to have the interrupt get/set priority API in RTEMS 6. The Cortex-M floating point issue is not yet fixed in the RTEMS master.

We should definitely wait with the release after the Gitlab migration is done and some basic CI is running.

I recently checked in a fix for powerpc and the AArch64 multilib changes for Cortex-A53 in GCC 13. To pick this up, the GCC commit needs to be updated. Maybe we should even wait for the GCC 13.3 release.
