Definition CSKYMCInstLower.cpp:37

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 const MCSpecifierExpr * create(const MCExpr *Expr, Spec S, MCContext &Ctx, SMLoc Loc=SMLoc())

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

@ MO_Immediate

Immediate operand.

@ MO_ConstantPoolIndex

Address of indexed Constant in Constant Pool.

@ MO_MCSymbol

MCSymbol reference (for debug/eh info)

@ MO_GlobalAddress

Address of a global value.

@ MO_RegisterMask

Mask of preserved registers.

@ MO_BlockAddress

Address of a basic block.

@ MO_MachineBasicBlock

MachineBasicBlock reference.

@ MO_Register

@ MO_ExternalSymbol

#define llvm_unreachable(msg)

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

This is an optimization pass for GlobalISel generic memory operations.
