Method Overview

Methods

ScheduleDAG(llvm::MachineFunction& mf)

Declared at: llvm/include/llvm/CodeGen/ScheduleDAG.h:571

Parameters

llvm::MachineFunction& mf

unsigned int VerifyScheduledDAG(bool isBottomUp)

Description

Adds custom features for a visualization of the ScheduleDAG.

Declared at: llvm/include/llvm/CodeGen/ScheduleDAG.h:600

Parameters

GraphWriter<llvm::ScheduleDAG*>& 

void clearDAG()

Description

Clears the DAG state (between regions).
