◆ getInstruction()

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

Returns the disassembly of a single instruction.

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.
- 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.
