void X86TargetMachine::addAnalysisPasses ( PassManagerBase & PM )

virtual

Register X86 analysis passes with a pass manager.

Reimplemented from llvm::LLVMTargetMachine.

Definition at line 131 of file X86TargetMachine.cpp.

References llvm::createBasicTargetTransformInfoPass(), and llvm::createX86TargetTransformInfoPass().

bool X86TargetMachine::addCodeEmitter	(	PassManagerBase &	,
		JITCodeEmitter &
	)

virtual

addCodeEmitter - This pass should be overridden by the target to add a code emitter, if supported. If this is not supported, 'true' should be returned.

Reimplemented from llvm::LLVMTargetMachine.

Definition at line 229 of file X86TargetMachine.cpp.

References llvm::createX86JITCodeEmitterPass().

TargetPassConfig * X86TargetMachine::createPassConfig ( PassManagerBase & PM )

virtual

createPassConfig - Create a pass configuration object to be used by addPassToEmitX methods for generating a pipeline of CodeGen passes.

Targets may override this to extend TargetPassConfig.

virtual const InstrItineraryData* llvm::X86TargetMachine::getInstrItineraryData ( ) const

inlinevirtual

getInstrItineraryData - Returns instruction itinerary data for the target or specific subtarget.

Reimplemented from llvm::TargetMachine.

Definition at line 63 of file X86TargetMachine.h.

virtual X86JITInfo* llvm::X86TargetMachine::getJITInfo ( )

inlinevirtual

getJITInfo - If this target supports a JIT, return information for it, otherwise return null.

virtual const X86RegisterInfo* llvm::X86TargetMachine::getRegisterInfo ( ) const

inlinevirtual

getRegisterInfo - If register information is available, return it. If not, return null. This is kept separate from RegInfo until RegInfo has details of graph coloring register allocation removed from it.
