  21 # This is the GCC build-, host- and target-specific configuration file
  22 # where a configuration type, as recognized and generated by config.bfd,
  23 # is mapped to different system-specific definitions and files.  This is
  24 # invoked by the autoconf-generated configure script, called for build,
  25 # host and target in that order, setting ${machine} to each.  Putting it
  26 # in a separate shell file lets us skip running autoconf when modifying
  27 # build-, host- and target-specific information.
  28
  29 # This file switches on the shell variable ${machine}, and also uses the
  30 # following shell variables:

  32 #  with_*               Various variables as set by configure.
  33 #
  34 #  enable_threads_flag  Either the name, yes or no depending on whether

  41 #                       requested.
