Inheritance diagram for llvm::Combiner:

Classes
class	WorkListMaintainer
	This class acts as the glue that joins the CombinerHelper to the overall Combine algorithm. More...

Public Member Functions
	Combiner (MachineFunction &MF, const CombinerInfo &CInfo, GISelValueTracking VT, GISelCSEInfo CSEInfo=nullptr)
	If CSEInfo is not null, then the Combiner will use CSEInfo as the observer and also create a CSEMIRBuilder.
	~Combiner () override
virtual bool	tryCombineAll (MachineInstr &I) const =0
bool	combineMachineInstrs ()
Public Member Functions inherited from llvm::GIMatchTableExecutor
virtual	~GIMatchTableExecutor ()=default
virtual void	setupGeneratedPerFunctionState (MachineFunction &MF)=0
virtual void	setupMF (MachineFunction &mf, GISelValueTracking vt, CodeGenCoverage covinfo=nullptr, ProfileSummaryInfo psi=nullptr, BlockFrequencyInfo bfi=nullptr)
	Setup per-MF executor state.

LLVM_ABI bool	isBaseWithConstantOffset (const MachineOperand &Root, const MachineRegisterInfo &MRI) const
	Return true if the specified operand is a G_PTR_ADD with a G_CONSTANT on the right-hand side.
LLVM_ABI bool	isObviouslySafeToFold (MachineInstr &MI, MachineInstr &IntoMI) const
	Return true if MI can obviously be folded into IntoMI.
