Do I need to keep the dc->user variable? > You also need to end the TB when assigning to SFC and DFC. Otherwise the > generated code is not in sync with the register contents. I checked that and SFC and DFC are assigned by movec, and movec ends with gen_lookup_tb() that set s->is_jmp to DISAS_UPDATE, and this forces an exit from the loop and tcg_gen_exit_tb() (like move_to_sr()).
