Header of lower AMDGPU MachineInstrs to their corresponding MCInst.

R600 Assembly printer class.

Provides R600 specific target descriptions.

AMDGPU R600 specific subclass of TargetSubtarget.

static SDValue lowerAddrSpaceCast(SDValue Op, SelectionDAG &DAG)

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

void EmitToStreamer(MCStreamer &S, const MCInst &Inst)

TargetMachine & TM

Target machine description.

MachineFunction * MF

The current machine function.

virtual const MCExpr * lowerConstant(const Constant *CV, const Constant *BaseCV=nullptr, uint64_t Offset=0)

Lower the specified LLVM Constant to an MCExpr.

MCContext & OutContext

This is the context for the output file that we are streaming.

std::unique_ptr< MCStreamer > OutStreamer

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

const MCSubtargetInfo & getSubtargetInfo() const

Return information about subtarget.

This is an important base class in LLVM.

This is an important class for using LLVM in a threaded context.

Context object for machine code objects.

Base class for the full range of assembler expressions which are needed for parsing.

Instances of this class represent a single low-level machine instruction.

void addOperand(const MCOperand Op)

void setOpcode(unsigned Op)

Instructions::const_iterator const_instr_iterator

Representation of each machine instruction.

const MCExpr * lowerConstant(const Constant *CV, const Constant *BaseCV, uint64_t Offset) override

Lower the specified LLVM Constant to an MCExpr.

Definition R600MCInstLower.cpp:77

void emitInstruction(const MachineInstr *MI) override

Implemented in AMDGPUMCInstLower.cpp.

Definition R600MCInstLower.cpp:49

const R600InstrInfo * getInstrInfo() const override

StringRef - Represent a constant reference to a string, i.e.

@ C

The default llvm calling convention, compatible with C.

This is an optimization pass for GlobalISel generic memory operations.

LLVM_ABI raw_fd_ostream & errs()

This returns a reference to a raw_ostream for standard error.
