  19 # This file requires GNU make!

  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
  27 # It can also update the C files in the features directory from their
  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 #
  41 # To generate specific C files, you can override the XMLTOC and
  42 # FEATURE_XMLFILES make variables:
  43 #
  44 #   make GDB=/path/to/gdb XMLTOC="xml files" FEATURE_XMLFILES="xml files" cfiles
  45
  46 # List of .dat files to create in ../regformats/
