Thanks for your patch. But I really appreciate your investigation into this issue. But I do not think this is a good solution. Since llvm can disassemble ADIW/SBIW correctly with `--mcpu=avr2` specified to `llvm-objdump`.

However there is still an underlying issue, which I have recorded as https://github.com/llvm/llvm-project/issues/146451 .
