Constructor & Destructor Documentation

ARMTargetMachine::ARMTargetMachine (  const Module &  M,
const std::string &  FS,
bool  isThumb = false
) 
 

TargetMachine ctor - Create an ARM architecture model.

Definition at line 71 of file ARMTargetMachine.cpp.

Member Function Documentation

bool ARMTargetMachine::addAssemblyEmitter (  PassManagerBase &  PM,
bool  Fast,
raw_ostream &  Out
)  [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 146 of file ARMTargetMachine.cpp.

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

bool ARMTargetMachine::addCodeEmitter (  PassManagerBase &  PM,
bool  Fast,
bool  DumpAsm,
MachineCodeEmitter &  MCE
)  [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 157 of file ARMTargetMachine.cpp.

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

bool ARMTargetMachine::addInstSelector (  PassManagerBase &  PM,
bool  Fast
)  [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 129 of file ARMTargetMachine.cpp.

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

bool ARMTargetMachine::addPreEmitPass (  PassManagerBase &  PM,
bool  Fast
)  [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 134 of file ARMTargetMachine.cpp.

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

bool ARMTargetMachine::addSimpleCodeEmitter (  PassManagerBase &  PM,
bool  Fast,
bool  DumpAsm,
MachineCodeEmitter &  MCE
)  [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.

Definition at line 173 of file ARMTargetMachine.cpp.

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

const TargetAsmInfo * ARMTargetMachine::createTargetAsmInfo (   )  const [virtual]
 

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

Reimplemented from llvm::TargetMachine.

Definition at line 116 of file ARMTargetMachine.cpp.

virtual const ARMFrameInfo* llvm::ARMTargetMachine::getFrameInfo (   )  const [inline, virtual]

virtual const ARMInstrInfo* llvm::ARMTargetMachine::getInstrInfo (   )  const [inline, virtual]
 

Reimplemented from llvm::TargetMachine.

Definition at line 48 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 50 of file ARMTargetMachine.h.

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 90 of file ARMTargetMachine.cpp.

Referenced by getModuleMatchQuality().

unsigned ARMTargetMachine::getModuleMatchQuality (  const Module &  M  )  [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 97 of file ARMTargetMachine.cpp.

References Module::getEndianness(), getJITMatchQuality(), Module::getPointerSize(), and Module::getTargetTriple().

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 51 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.
