• public bool combineMachineInstrs(llvm::MachineFunction & MF, llvm::GISelCSEInfo * CSEInfo)

Methods

¶Combiner(llvm::CombinerInfo& CombinerInfo,
         const llvm::TargetPassConfig* TPC)

Declared at: llvm/include/llvm/CodeGen/GlobalISel/Combiner.h:28

Parameters

llvm::CombinerInfo& CombinerInfo

const llvm::TargetPassConfig* TPC

¶bool combineMachineInstrs(
    llvm::MachineFunction& MF,
    llvm::GISelCSEInfo* CSEInfo)

Description

If CSEInfo is not null, then the Combiner will setup observer for CSEInfo and instantiate a CSEMIRBuilder. Pass nullptr if CSE is not needed.
