@Patryk27 I hope you don't mind that I have a question again about the LLVM code base. I made a number of PRs which complete disassembly of AVR files with `llvm_objdump`. This one is the last, it adds `MOVW` and `ADIW/SBIW (SUBIW)`. All other PRs decode fine, but this one leaves the `ADIW/SBIW` as:

```
      f4: 02 96         adiw    r24, <unknown>
```

so the opcode mnemonic and register are OK, but the immediate is not. Any hints?
