ArrayRef - Represent a constant reference to an array (0 or more elements consecutively in memory),...

size_t size() const

size - Get the array size.

Context object for machine code objects.

Superclass for all disassemblers.

DecodeStatus

Ternary decode status.

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

void addOperand(const MCOperand Op)

static MCOperand createReg(MCRegister Reg)

static MCOperand createImm(int64_t Val)

Generic base class for all target subtargets.

Target - Wrapper for Target specific information.

This class implements an extremely fast bulk output stream that can only output to a stream.

uint32_t read32le(const void *P)

This is an optimization pass for GlobalISel generic memory operations.

Target & getTheLoongArch64Target()

constexpr bool isUInt(uint64_t x)

Checks if an unsigned integer fits into the given bit width.

Target & getTheLoongArch32Target()

constexpr int64_t SignExtend64(uint64_t x)

Sign-extend the number in the bottom B bits of X to a 64-bit integer.

static void RegisterMCDisassembler(Target &T, Target::MCDisassemblerCtorTy Fn)

RegisterMCDisassembler - Register a MCDisassembler implementation for the given target.
