virtual const ARMInstrInfo* llvm::ARMTargetMachine::getInstrInfo

(

)

const [inline, virtual]

Reimplemented from llvm::TargetMachine.

Definition at line 49 of file ARMTargetMachine.h.

virtual const ARMFrameInfo* llvm::ARMTargetMachine::getFrameInfo

(

)

const [inline, virtual]

Reimplemented from llvm::TargetMachine.

Definition at line 50 of file ARMTargetMachine.h.

virtual ARMJITInfo* llvm::ARMTargetMachine::getJITInfo

(

)

[inline, virtual]

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

Reimplemented from llvm::TargetMachine.

Definition at line 51 of file ARMTargetMachine.h.

virtual const ARMRegisterInfo* llvm::ARMTargetMachine::getRegisterInfo

(

)

const [inline, virtual]

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.

Reimplemented from llvm::TargetMachine.

Definition at line 52 of file ARMTargetMachine.h.

References llvm::ARMInstrInfo::getRegisterInfo().

virtual const TargetData* llvm::ARMTargetMachine::getTargetData

const [inline, virtual]

Reimplemented from llvm::TargetMachine.

Definition at line 55 of file ARMTargetMachine.h.

virtual const ARMSubtarget* llvm::ARMTargetMachine::getSubtargetImpl

(

)

const [inline, virtual]

getSubtargetImpl - virtual method implemented by subclasses that returns a reference to that target's TargetSubtarget-derived member variable.

Reimplemented from llvm::TargetMachine.

Definition at line 56 of file ARMTargetMachine.h.

virtual ARMTargetLowering* llvm::ARMTargetMachine::getTargetLowering

unsigned ARMTargetMachine::getModuleMatchQuality

(

const Module &

)

[static]

getModuleMatchQuality - This static method should be implemented by targets to indicate how closely they match the specified module. This is used by the LLC tool to determine which target to use when an explicit -march option is not specified. If a target returns zero, it will never be chosen without an explicit -march option.

Reimplemented from llvm::TargetMachine.

Reimplemented in llvm::ThumbTargetMachine.

Definition at line 106 of file ARMTargetMachine.cpp.

References llvm::Module::AnyEndianness, llvm::Module::AnyPointerSize, llvm::Module::getEndianness(), getJITMatchQuality(), llvm::Module::getPointerSize(), llvm::Module::getTargetTriple(), llvm::Module::LittleEndian, and llvm::Module::Pointer32.

unsigned ARMTargetMachine::getJITMatchQuality

(

)

[static]

getJITMatchQuality - This static method should be implemented by targets that provide JIT capabilities to indicate how suitable they are for execution on the current host. If a value of 0 is returned, the target will not be used unless an explicit -march option is used.

Reimplemented from llvm::TargetMachine.

Reimplemented in llvm::ThumbTargetMachine.

Definition at line 99 of file ARMTargetMachine.cpp.

Referenced by getModuleMatchQuality().

const TargetAsmInfo * ARMTargetMachine::createTargetAsmInfo

(

)

const [virtual]

createTargetAsmInfo - Create a new instance of target specific asm information.

Reimplemented from llvm::TargetMachine.

Definition at line 125 of file ARMTargetMachine.cpp.

References llvm::ARMSubtarget::isDarwin, llvm::ARMSubtarget::isELF, and llvm::ARMSubtarget::TargetType.

bool ARMTargetMachine::addInstSelector	(	PassManagerBase &	,
		bool
	)			[virtual]

Target-Independent Code Generator Pass Configuration Options.

addInstSelector - This method should add any "last minute" LLVM->LLVM passes, then install an instruction selector pass, which converts from LLVM code to machine instructions.

Reimplemented from llvm::LLVMTargetMachine.

Definition at line 138 of file ARMTargetMachine.cpp.

References llvm::PassManagerBase::add(), and llvm::createARMISelDag().

bool ARMTargetMachine::addPreEmitPass	(	PassManagerBase &	,
		bool
	)			[virtual]

addPreEmitPass - This pass may be implemented by targets that want to run passes immediately before machine code is emitted. This should return true if -print-machineinstrs should print out the code after the passes.

Reimplemented from llvm::LLVMTargetMachine.

Definition at line 143 of file ARMTargetMachine.cpp.

References llvm::PassManagerBase::add(), llvm::createARMConstantIslandPass(), llvm::createARMLoadStoreOptimizationPass(), llvm::createIfConverterPass(), DisableIfConversion, DisableLdStOpti, and llvm::ARMSubtarget::isThumb().

bool ARMTargetMachine::addAssemblyEmitter	(	PassManagerBase &	,
		bool	,
		raw_ostream &
	)			[virtual]

addAssemblyEmitter - This pass should be overridden by the target to add the asmprinter, if asm emission is supported. If this is not supported, 'true' should be returned.

Reimplemented from llvm::LLVMTargetMachine.

Definition at line 155 of file ARMTargetMachine.cpp.

References llvm::PassManagerBase::add(), and AsmPrinterCtor.

bool ARMTargetMachine::addCodeEmitter	(	PassManagerBase &	,
		bool	,
		bool	,
		MachineCodeEmitter &
	)			[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. If DumpAsm is true, the generated assembly is printed to cerr.

Reimplemented from llvm::LLVMTargetMachine.

Definition at line 166 of file ARMTargetMachine.cpp.

References llvm::PassManagerBase::add(), AsmPrinterCtor, llvm::createARMCodeEmitterPass(), llvm::Reloc::Default, llvm::errs(), llvm::TargetMachine::setRelocationModel(), and llvm::Reloc::Static.

bool ARMTargetMachine::addSimpleCodeEmitter	(	PassManagerBase &	,
		bool	,
		bool	,
		MachineCodeEmitter &
	)			[virtual]

addSimpleCodeEmitter - This pass should be overridden by the target to add a code emitter (without setting flags), if supported. If this is not supported, 'true' should be returned. If DumpAsm is true, the generated assembly is printed to cerr.

Reimplemented from llvm::LLVMTargetMachine.
