Hi Matthias,

I agree that this would be nice, so I've had a play around it seems non-trivial to get a default configuration without breaking some tests. It is simple enough to predicate the PostRA scheduler on the availability of Thumb2 but this causes breakages for Swift. Do you know why we don't want to enable PostRA for MIScheduled arm cores? PostRA is used on almost all of the AArch64 cores along with the MIScheduler, so I'm wondering why the two approaches are different.

Thanks,
sam
