void EmitInstruction(const MachineInstr *MI) override
Implemented in AMDGPUMCInstLower.cpp.
This class represents lattice values for constants.
Definition: AllocatorList.h:23
const MCExpr * lowerConstant(const Constant *CV) override
Lower the specified LLVM Constant to an MCExpr.
bool runOnMachineFunction(MachineFunction &MF) override
Emit the specified function out to the OutStreamer.
MachineFunction * MF
The current machine function.
Definition: AsmPrinter.h:96
AsmPrinter * createR600AsmPrinterPass(TargetMachine &TM, std::unique_ptr< MCStreamer > &&Streamer)
Base class for the full range of assembler expressions which are needed for parsing.
Definition: MCExpr.h:35
This is an important base class in LLVM.
Definition: Constant.h:41
TargetMachine & TM
Target machine description.
Definition: AsmPrinter.h:81
StringRef getPassName() const override
getPassName - Return a nice clean name for a pass.
This class is intended to be used as a driving class for all asm writers.
Definition: AsmPrinter.h:78
Representation of each machine instruction.
Definition: MachineInstr.h:63
R600AsmPrinter(TargetMachine &TM, std::unique_ptr< MCStreamer > Streamer)
Primary interface to the complete machine description for the target machine.
Definition: TargetMachine.h:65
IRTranslator LLVM IR MI
StringRef - Represent a constant reference to a string, i.e.
Definition: StringRef.h:48
