     * avr-tdep.c (avr_remote_translate_xfer_address): Delete function.
     (avr_gdbarch_init): Remove avr_call_dummy_words variable.
     Don't set deprecated_call_dummy_words.
     Remove commented out set_gdbarch_believe_pcc_promotion() call.
     Don't set remote_translate_xfer_address.
     (avr_io_reg_read_command): Remove commented out debug printf.
     Wrap a long line.
