Methods
¶DefaultVLIWScheduler(llvm::MachineFunction& MF,
llvm::MachineLoopInfo& MLI,
llvm::AAResults* AA)
DefaultVLIWScheduler(llvm::MachineFunction& MF,
llvm::MachineLoopInfo& MLI,
llvm::AAResults* AA)Declared at: llvm/lib/CodeGen/DFAPacketizer.cpp:112
Parameters
¶void addMutation(
std::unique_ptr<ScheduleDAGMutation> Mutation)
void addMutation(
std::unique_ptr<ScheduleDAGMutation> Mutation)Description
DefaultVLIWScheduler takes ownership of the Mutation object.
Declared at: llvm/lib/CodeGen/DFAPacketizer.cpp:119
Parameters
- std::unique_ptr<ScheduleDAGMutation> Mutation
¶void postprocessDAG()
void postprocessDAG()Description
Apply each ScheduleDAGMutation step in order.
Declared at: llvm/lib/CodeGen/DFAPacketizer.cpp:124
¶void schedule()
void schedule()Description
Orders nodes according to selected style. Typically, a scheduling algorithm will implement schedule() without overriding enterRegion() or exitRegion().
