  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
  29 # configured for the correct architecture, so the files are again kept
  30 # in the GDB repository.  To generate C files:
  31 #   make GDB=/path/to/gdb XMLTOC="xml files" cfiles
