class GISelCSEAnalysisWrapper

Declaration

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

Description

Simple wrapper that does the following. 1) Lazily evaluate the MachineFunction to compute CSEable instructions. 2) Allows configuration of which instructions are CSEd through CSEConfig object. Provides a method called get which takes a CSEConfig object.

Member Variables

private llvm::GISelCSEInfo Info

private llvm::MachineFunction* MF = nullptr

private bool AlreadyComputed = false

Method Overview

• public llvm::GISelCSEInfo & get(std::unique_ptr<CSEConfigBase> CSEOpt, bool ReCompute = false)
• public void releaseMemory()
• public void setComputed(bool Computed)
• public void setMF(llvm::MachineFunction & MFunc)

Methods

¶llvm::GISelCSEInfo& get(
    std::unique_ptr<CSEConfigBase> CSEOpt,
    bool ReCompute = false)

Description

Takes a CSEConfigBase object that defines what opcodes get CSEd. If CSEConfig is already set, and the CSE Analysis has been preserved, it will not use the new CSEOpt(use Recompute to force using the new CSEOpt).
