#
# This script is for generating the .io_reg field initializer of the
# DevSuppDefn for a specfic device. The input should be one of the io*.h files
# provided by avr-libc in the include/avr/ directory.
#
# Usage: io_gen.py <io_header>
#
# This best way to use this script is while using vim to edit the ioreg.cc.
# You can run the script from vim and have the output of the script inserted
# directly into the ioreg.cc file with a command like this:
#
# :r!../misc/io_gen.py ~/dev/tools/avr-libc-cvs/include/avr/iomega128.h
#
import os, sys, re

re_io8 = re.compile (base_regx % ('_SFR_IO8'))
re_mem8 = re.compile (base_regx % ('_SFR_MEM8'))
# Open the input file.
