Emit the expression Value into the output as a native integer of the given Size bytes.
void reset() override
state management
void emitLabel(MCSymbol *Symbol, SMLoc Loc=SMLoc()) override
Emit a label for Symbol into the current section.
Base class for the full range of assembler expressions which are needed for parsing.
This is an instance of a target assembly language printer that converts an MCInst to valid target ass...
Instances of this class represent a single low-level machine instruction.
void emitFill(const MCExpr &NumBytes, uint64_t FillValue, SMLoc Loc=SMLoc()) override
Emit Size bytes worth of the value specified by FillValue.
void emitBytes(StringRef Data) override
Emit the bytes in Data into the output.
void emitInstruction(const MCInst &Inst, const MCSubtargetInfo &STI) override
Emit the given Instruction into the current section.
This represents a section on linux, lots of unix variants and some bare metal systems.
Instances of this class represent a uniqued identifier for a section in the current translation unit.
Streaming machine code generation interface.
