◆ schedule()

void SIScheduleDAGMI::schedule ( )
overridevirtual

Implement ScheduleDAGInstrs interface for scheduling a sequence of reorderable instructions.

schedule - Called back from MachineScheduler::runOnMachineFunction after setting up the current scheduling region.

[RegionBegin, RegionEnd) only includes instructions that have DAG nodes, not scheduling boundaries.

This is a skeletal driver, with all the functionality pushed into helpers, so that it can be easily extended by experimental schedulers. Generally, implementing MachineSchedStrategy should be sufficient to implement a new scheduling algorithm. However, if a scheduler further subclasses ScheduleDAGMILive then it will want to override this virtual method in order to update any specialized state.

Reimplemented from llvm::ScheduleDAGMILive.
