2269408Sache# This is the GCC host-specific configuration file
2369408Sache# where a configuration type is mapped to different system-specific
2469408Sache# definitions and files.  This is invoked by the autoconf-generated
2569408Sache# configure script.  Putting it in a separate shell file lets us skip
2669408Sache# running autoconf when modifying host-specific information.
2769408Sache
2869408Sache# This file switches on the shell variable ${host}.  As much of this as
2969408Sache# is reasonable should be replaced with autoconf tests in the future.
3069408Sache
3169408Sache# This file sets the following shell variables for use by the
3269408Sache# autoconf-generated configure script:
3369408Sache#
3469408Sache#  host_xm_file         List of files to include when compiling for the
3569408Sache#                       host machine.
3669408Sache#
3769408Sache#  host_xm_defines      List of macros to define when compiling for the
3869408Sache#                       host machine.
3969408Sache#
4069408Sache#  host_xmake_file      List of host-specific makefile-fragments.
4169408Sache#
4269408Sache#  host_exeext          Set to the suffix, if the host machine requires
4369408Sache#                       executables to have a file name suffix.
4469408Sache#
4569408Sache#  host_extra_objs      List of extra host-dependent objects that should
4669408Sache#                       be linked into the compiler proper.
4769408Sache#
4869408Sache#  host_extra_gcc_objs  List of extra host-dependent objects that should
4969408Sache#                       be linked into the gcc driver.
5069408Sache#
5169408Sache#  out_host_hook_obj    An object file that provides the host hooks.
5269408Sache
5369408Sache# When setting any of these variables, check to see if a corresponding
5469408Sache# variable is present in config.build; if so, you will likely want to 
5569408Sache# set it in both places.
