[PATCH] D15667: [MachineScheduler] Handle regmasks and allow calls to be rescheduled.

[Jonas Paulsson via llvm-commits]

jonpa added a comment.

I noticed the comment phrasing including "currently" about the scheduler not handling calls, so I thought there might be some general interest.

For SystemZ this may be of interest also post-ra for the purpose of decoding, but that is just experimentation so far.

More scheduling freedom pre-ra would also be possible, and perhaps this would be good in some cases.

Otherwise, I am not really sure at the moment how needed this is.
