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

[Jonas Paulsson via llvm-commits]

jonpa added a comment.

Considering that different instructions may have different grouping rules, meaning that in some cases some instructions can only go in certain slots and so on, a greater freedom for the scheduler should generally be good. I think I became interested in this while looking at some functions with long chains of calls. But, as I said, this is just experimentation so far.
