void VLIWMachineScheduler::schedule

(

)

[override, virtual]

Schedule - This is called back from ScheduleDAGInstrs::Run() when it's time to do some work.

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.

Reimplemented from llvm::ScheduleDAGMILive.
