  22 # This is the GCC host-specific configuration file
  23 # where a configuration type is mapped to different system-specific
  24 # definitions and files.  This is invoked by the autoconf-generated
  25 # configure script.  Putting it in a separate shell file lets us skip
  26 # running autoconf when modifying host-specific information.
  27
  28 # This file switches on the shell variable ${host}.  As much of this as
  29 # is reasonable should be replaced with autoconf tests in the future.
  30
  31 # This file sets the following shell variables for use by the
  32 # autoconf-generated configure script:
  33 #
  34 #  host_xm_file         List of files to include when compiling for the
  35 #                       host machine.
  36 #
  37 #  host_xm_defines      List of macros to define when compiling for the
  38 #                       host machine.
  39 #
  40 #  host_xmake_file      List of host-specific makefile-fragments.
  41 #
  42 #  host_exeext          Set to the suffix, if the host machine requires
  43 #                       executables to have a file name suffix.
  44 #
  45 #  host_extra_objs      List of extra host-dependent objects that should
  46 #                       be linked into the compiler proper.
  47 #
  48 #  host_extra_gcc_objs  List of extra host-dependent objects that should
  49 #                       be linked into the gcc driver.
  50 #
  51 #  out_host_hook_obj    An object file that provides the host hooks.
  52
  53 # When setting any of these variables, check to see if a corresponding
  54 # variable is present in config.build; if so, you will likely want to
  55 # set it in both places.
  56
