Checklist

• I have searched for a similar issue in this repository and did not find one.

Description

Analyzer message:
V579 The ZydisDecoderDecodeFull function receives the pointer and its size as arguments. It is possibly a error. Inspect the third argument. decoder.cpp 29

Instruction longer than 8 byte will be cut off. A highly probable error or very strange code that requires a comment\simplification.

void DecoderImpl::printInstruction(void* code, u64 address) {
  ZydisDecodedInstruction instruction;
  ZydisDecodedOperand operands[ZYDIS_MAX_OPERAND_COUNT_VISIBLE];
  ZyanStatus status =
    ZydisDecoderDecodeFull(&m_decoder, code, sizeof(code), 
                           &instruction, operands);
  if (!ZYAN_SUCCESS(status)) {
    fmt::print("decode instruction failed at {}\n", fmt::ptr(code));
  } else {
    printInst(instruction, operands, address);
  }
}
