class SchedulingPriorityQueue

Declaration

class SchedulingPriorityQueue { /* full declaration omitted */ };

Description

This interface is used to plug different priorities computation algorithms into the list scheduler. It implements the interface of a standard priority queue, where nodes are inserted in arbitrary order and returned in priority order. The computation of the priority and the representation of the queue are totally up to the implementation to decide.

virtual void push(llvm::SUnit* U)

Declared at: llvm/include/llvm/CodeGen/ScheduleDAG.h:525

Parameters

llvm::SUnit* U

void push_all(const std::vector<SUnit*>& Nodes)

Declared at: llvm/include/llvm/CodeGen/ScheduleDAG.h:527

Parameters

const std::vector<SUnit*>& Nodes

virtual void releaseState()

Declared at: llvm/include/llvm/CodeGen/ScheduleDAG.h:512

virtual void remove(llvm::SUnit* SU)

Declared at: llvm/include/llvm/CodeGen/ScheduleDAG.h:534

Parameters

llvm::SUnit* SU

virtual void scheduledNode(llvm::SUnit*)

Description

As each node is scheduled, this method is invoked. This allows the priority function to adjust the priority of related unscheduled nodes, for example.

Parameters

llvm::SUnit* 

void setCurCycle(unsigned int Cycle)

Declared at: llvm/include/llvm/CodeGen/ScheduleDAG.h:545

Parameters

unsigned int Cycle

virtual bool tracksRegPressure() const

virtual void unscheduledNode(llvm::SUnit*)

Declared at: llvm/include/llvm/CodeGen/ScheduleDAG.h:543

Parameters

llvm::SUnit* 

virtual void updateNode(const llvm::SUnit* SU)

Declared at: llvm/include/llvm/CodeGen/ScheduleDAG.h:511

Parameters

const llvm::SUnit* SU
