Thanks for your suggestion. I have done
1. Add a new MIR test to show register state changes.
2. Corrent wrong register state when expanding the ASRW7/ASRW14/ASRW15 pseudo instructions.
3. Add `-verify-machineinstrs` option to the `/llvm/test/CodeGen/AVR/sign-extension.ll`
4. Change the register class of ASRWNRd from `DLDREGS` to `DREGS`.
