21# This Makefile updates files in ../regformats from their XML master
22# copies. Because this relies on xsltproc, it is not normally run
23# during the build process; it should be run by hand when one of the
24# affected XML files is changed, and the results should be kept in the
25# GDB repository.
26
81adfced 27# It can also update the C files in the features directory from their
db74e4ba
PA
28# XML master copies. This relies on a GDB linked with expat and that
29# is configured to include support for the architecture, so the files
30# are kept in the GDB repository.
31#
32# By default we'll generate all C files, and you must point make at a
33# GDB that has been configured with --enable-targets=all:
34#
35# make GDB=/path/to/gdb cfiles
36#
37# To regenerate all C files from scratch:
38#
39# make GDB=/path/to/gdb clean-cfiles cfiles
40#
89abbcc2
AH
41# To generate specific C files, you can override the XMLTOC and
42# FEATURE_XMLFILES make variables:
db74e4ba 43#
89abbcc2 44# make GDB=/path/to/gdb XMLTOC="xml files" FEATURE_XMLFILES="xml files" cfiles
81adfced 45
