# This file requires GNU make!

# This Makefile updates files in ../regformats from their XML master
# copies.  Because this relies on xsltproc, it is not normally run
# during the build process; it should be run by hand when one of the
# affected XML files is changed, and the results should be kept in the
# GDB repository.

# It can also update the C files in the features directory from their
# XML master copies.  This relies on a GDB linked with expat and that
# is configured to include support for the architecture, so the files
# are kept in the GDB repository.
#
# By default we'll generate all C files, and you must point make at a
# GDB that has been configured with --enable-targets=all:
#
#   make GDB=/path/to/gdb cfiles
#
# To regenerate all C files from scratch:
#
#   make GDB=/path/to/gdb clean-cfiles cfiles
#
# To generate specific C files, you can override the XMLTOC and
# FEATURE_XMLFILES make variables:
#
#   make GDB=/path/to/gdb XMLTOC="xml files" FEATURE_XMLFILES="xml files" cfiles

# List of .dat files to create in ../regformats/
