Member Function Documentation

◆ getInstruction()

DecodeStatus M68kDisassembler::getInstruction	(	MCInst &	Instr,
		uint64_t &	Size,
		ArrayRef< uint8_t >	Bytes,
		uint64_t	Address,
		raw_ostream &	CStream ) const

overridevirtual

Returns the disassembly of a single instruction.

Parameters

Instr	- An MCInst to populate with the contents of the instruction.
Size	- A value to populate with the size of the instruction, or the number of bytes consumed while attempting to decode an invalid instruction.
Address	- The address, in the memory space of region, of the first byte of the instruction.
Bytes	- A reference to the actual bytes of the instruction.
CStream	- The stream to print comments and annotations on.

Returns: - MCDisassembler::Success if the instruction is valid, MCDisassembler::SoftFail if the instruction was disassemblable but invalid, MCDisassembler::Fail if the instruction was invalid.

Implements llvm::MCDisassembler.
