# This is the GCC host-specific configuration file
# where a configuration type is mapped to different system-specific
# definitions and files.  This is invoked by the autoconf-generated
# configure script.  Putting it in a separate shell file lets us skip
# running autoconf when modifying host-specific information.

# This file switches on the shell variable ${host}.  As much of this as
# is reasonable should be replaced with autoconf tests in the future.

# This file sets the following shell variables for use by the
# autoconf-generated configure script:
#
#  host_xm_file         List of files to include when compiling for the
#                       host machine.
#
#  host_xm_defines      List of macros to define when compiling for the
#                       host machine.
#
#  host_xmake_file      List of host-specific makefile-fragments.
#
#  host_exeext          Set to the suffix, if the host machine requires
#                       executables to have a file name suffix.
#
#  host_extra_objs      List of extra host-dependent objects that should
#                       be linked into the compiler proper.
#
#  host_extra_gcc_objs  List of extra host-dependent objects that should
#                       be linked into the gcc driver.
#
#  out_host_hook_obj    An object file that provides the host hooks.

# When setting any of these variables, check to see if a corresponding
# variable is present in config.build; if so, you will likely want to 
# set it in both places.

# Default settings.
