class InstrPostProcess

Declaration

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

Description

Class which can be overriden by targets to modify the mca::Instruction objects before the pipeline starts. A common usage of this class is to add immediate operands to certain instructions or to remove Defs/Uses from an instruction where the schedulinng model is incorrect.

Member Variables

protected const llvm::MCSubtargetInfo& STI

protected const llvm::MCInstrInfo& MCII

Method Overview

• public InstrPostProcess(const llvm::MCSubtargetInfo & STI, const llvm::MCInstrInfo & MCII)
• public virtual void postProcessInstruction(std::unique_ptr<Instruction> & Inst, const llvm::MCInst & MCI)
• public virtual void resetState()
• public virtual ~InstrPostProcess()

Methods

¶InstrPostProcess(const llvm::MCSubtargetInfo& STI,
                 const llvm::MCInstrInfo& MCII)

Declared at: llvm/include/llvm/MCA/CustomBehaviour.h:41

Parameters

const llvm::MCSubtargetInfo& STI

const llvm::MCInstrInfo& MCII

¶virtual void postProcessInstruction(
    std::unique_ptr<Instruction>& Inst,
    const llvm::MCInst& MCI)

Description

This method can be overriden by targets to modify the mca::Instruction object after it has been lowered from the MCInst. This is generally a less disruptive alternative to modifying the scheduling model.

std::unique_ptr<Instruction>& Inst

const llvm::MCInst& MCI
