# 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.
#
# host_can_use_collect2 Set to yes normally; to no if the host cannot
# link or otherwise use collect2
# use_long_long_for_widest_fast_int Set this to 'yes' if 'long long'
# (or '__int64') is wider than 'long' but still
# efficeiently supported by the host hardware.
# Only affects compile speed. Default is 'no'.
# 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.
