Hi All,

The description of ScheduleDAGMILive [1] says:

ScheduleDAGMILive is an implementation of ScheduleDAGInstrs that

schedules machine instructions while updating LiveIntervals and tracking regpressure.

Does the live interval and register pressure part of ScheduleDAGMILive mean the subclass of ScheduleDAGMILive is a pre-RA scheduler? I assume the post-RA scheduler no need to take care of live interval and register pressure, since RA is done already.

Thanks.
