int SchedulingCost(ReadyQueue &Q, SUnit *SU, SchedCandidate &Candidate, RegPressureDelta &Delta, bool verbose) override
Single point to compute overall scheduling cost.
bool hasDependence(const SUnit *SUd, const SUnit *SUu) override
Return true if there is a dependence between SUd and SUu.
Helpers for implementing custom MachineSchedStrategy classes.
Scheduling unit. This is a node in the scheduling DAG.
Definition: ScheduleDAG.h:242
Provide an instruction scheduling machine model to CodeGen passes.
TargetSubtargetInfo - Generic base class for all target subtargets.
VLIWResourceModel(const TargetSubtargetInfo &STI, const TargetSchedModel *SM)
This is an optimization pass for GlobalISel generic memory operations.
