Provides R600 specific target descriptions.

AMDGPU R600 specific subclass of TargetSubtarget.

uint32_t getLDSSize() const

This class is intended to be used as a driving class for all asm writers.

const TargetLoweringObjectFile & getObjFileLowering() const

Return information about object file lowering.

TargetMachine & TM

Target machine description.

MachineFunction * MF

The current machine function.

virtual void SetupMachineFunction(MachineFunction &MF)

This should be called when a new MachineFunction is being processed from runOnMachineFunction.

void emitFunctionBody()

This method emits the body and trailer for a function.

AsmPrinter(TargetMachine &TM, std::unique_ptr< MCStreamer > Streamer, char &ID=AsmPrinter::ID)

std::unique_ptr< MCStreamer > OutStreamer

This is the MCStreamer object for the file we are generating.

bool isVerbose() const

Return true if assembly output should contain comments.

Context object for machine code objects.

MCContext & getContext() const

This represents a section on linux, lots of unix variants and some bare metal systems.

const TargetSubtargetInfo & getSubtarget() const

getSubtarget - Return the subtarget for which this machine code is being compiled.

Ty * getInfo()

getInfo - Keep track of various per-function pieces of information for backends that would like to do...

Representation of each machine instruction.

MachineOperand class - Representation of each machine instruction operand.

bool isReg() const

isReg - Tests if this is a MO_Register operand.

getReg - Returns the register number.

bool runOnMachineFunction(MachineFunction &MF) override

Emit the specified function out to the OutStreamer.

Definition R600AsmPrinter.cpp:103

StringRef getPassName() const override

getPassName - Return a nice clean name for a pass.

AsmPrinter * createR600AsmPrinterPass(TargetMachine &TM, std::unique_ptr< MCStreamer > &&Streamer)

Definition R600AsmPrinter.cpp:31

uint64_t alignTo(uint64_t Size, Align A)

Returns a multiple of A needed to store Size bytes.

OutputIt move(R &&Range, OutputIt Out)

Provide wrappers to std::move which take ranges instead of having to pass begin/end explicitly.

Implement std::hash so that hash_code can be used in STL containers.

This struct is a compact representation of a valid (non-zero power of two) alignment.
