20# This is the GCC host-specific configuration file
21# where a configuration type is mapped to different system-specific
22# definitions and files.  This is invoked by the autoconf-generated
23# configure script.  Putting it in a separate shell file lets us skip
24# running autoconf when modifying host-specific information.
25
26# This file switches on the shell variable ${host}.  As much of this as
27# is reasonable should be replaced with autoconf tests in the future.
28
29# This file sets the following shell variables for use by the
30# autoconf-generated configure script:
31#
32#  host_xm_file         List of files to include when compiling for the
33#                       host machine.
34#
35#  host_xm_defines      List of macros to define when compiling for the
36#                       host machine.
37#
38#  host_xmake_file      List of host-specific makefile-fragments.
39#
40#  host_exeext          Set to the suffix, if the host machine requires
41#                       executables to have a file name suffix.
42#
43#  host_extra_objs      List of extra host-dependent objects that should
44#                       be linked into the compiler proper.
45#
46#  host_extra_gcc_objs  List of extra host-dependent objects that should
47#                       be linked into the gcc driver.
48#
49#  out_host_hook_obj    An object file that provides the host hooks.
50#
51#  host_can_use_collect2 Set to yes normally; to no if the host cannot
52#			link or otherwise use collect2
53#
54#  use_long_long_for_widest_fast_int Set this to 'yes' if 'long long'
55#			(or '__int64') is wider than 'long' but still
56#			efficeiently supported by the host hardware.
57#			Only affects compile speed.  Default is 'no'.
58#
59#  host_lto_plugin_soname Set this to the name to which the LTO linker
60#			plugin gets compiled on this host, if it is
61#			different from the default "liblto_plugin.so".
62
63# When setting any of these variables, check to see if a corresponding
64# variable is present in config.build; if so, you will likely want to
65# set it in both places.
66
67# Default settings.
