Andrew Trick 92e946630d Introducing a new method of tracking register pressure. We can't ... precisely track pressure on a selection DAG, but we can at least keep it balanced. This design accounts for various interesting aspects of selection DAGS: register and subregister copies, glued nodes, dead nodes, unused registers, etc. Added SUnit::NumRegDefsLeft and ScheduleDAGSDNodes::RegDefIter. Note: I disabled PrescheduleNodesWithMultipleUses when register pressure is enabled, based on no evidence other than I don't think it makes sense to have both enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124853 91177308-0d34-0410-b5e6-96231b3b80d8		2011-02-04 03:18:17 +00:00
