static MCOperand lowerSymbolOperand(const MachineOperand &MO, MCSymbol *Sym, const AsmPrinter &AP)

Definition LoongArchMCInstLower.cpp:26

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

virtual MCSymbol * GetCPISymbol(unsigned CPID) const

Return the symbol for the specified constant pool entry.

MCSymbol * GetJTISymbol(unsigned JTID, bool isLinkerPrivate=false) const

Return the symbol for the specified jump table entry.

MCSymbol * getSymbolPreferLocal(const GlobalValue &GV) const

Similar to getSymbol() but preferred for references.

MCContext & OutContext

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

MCSymbol * GetBlockAddressSymbol(const BlockAddress *BA) const

Return the MCSymbol used to satisfy BlockAddress uses of the specified basic block.

MCSymbol * GetExternalSymbolSymbol(const Twine &Sym) const

Return the MCSymbol for the specified ExternalSymbol.

static const LoongArchMCExpr * create(const MCExpr *Expr, uint16_t S, MCContext &Ctx, bool Hint=false)

static const MCBinaryExpr * createAdd(const MCExpr *LHS, const MCExpr *RHS, MCContext &Ctx, SMLoc Loc=SMLoc())

static LLVM_ABI const MCConstantExpr * create(int64_t Value, MCContext &Ctx, bool PrintInHex=false, unsigned SizeInBytes=0)

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)

Instances of this class represent operands of the MCInst class.

static MCOperand createExpr(const MCExpr *Val)

static MCOperand createReg(MCRegister Reg)

static MCOperand createImm(int64_t Val)

static const MCSymbolRefExpr * create(const MCSymbol *Symbol, MCContext &Ctx, SMLoc Loc=SMLoc())

MCSymbol - Instances of this class represent a symbol name in the MC file, and MCSymbols are created ...

LLVM_ABI MCSymbol * getSymbol() const

Return the MCSymbol for this basic block.

Representation of each machine instruction.

MachineOperand class - Representation of each machine instruction operand.

const GlobalValue * getGlobal() const

MachineBasicBlock * getMBB() const

bool isJTI() const

isJTI - Tests if this is a MO_JumpTableIndex operand.

const BlockAddress * getBlockAddress() const

MachineOperandType getType() const

getType - Returns the MachineOperandType for this operand.

const char * getSymbolName() const

getReg - Returns the register number.

@ MO_Immediate

Immediate operand.

@ MO_ConstantPoolIndex

Address of indexed Constant in Constant Pool.

@ MO_GlobalAddress

Address of a global value.

@ MO_RegisterMask

Mask of preserved registers.

Address of a basic block.

@ MO_MachineBasicBlock

MachineBasicBlock reference.

@ MO_Register

@ MO_ExternalSymbol

Name of external global symbol.

@ MO_JumpTableIndex

Address of indexed Jump Table for switch.

int64_t getOffset() const

Return the offset from the symbol in this operand.

bool isMBB() const

isMBB - Tests if this is a MO_MachineBasicBlock operand.

#define llvm_unreachable(msg)

Marks that the current location is not supposed to be reachable.

static bool hasRelaxFlag(const MachineOperand &MO)

static unsigned getDirectFlags(const MachineOperand &MO)

This is an optimization pass for GlobalISel generic memory operations.
