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#  host_can_use_collect2 Set to yes normally; to no if the host cannot
54#			link or otherwise use collect2
55#  use_long_long_for_widest_fast_int Set this to 'yes' if 'long long'
56#			(or '__int64') is wider than 'long' but still
57#			efficeiently supported by the host hardware.
58#			Only affects compile speed.  Default is 'no'.
59
60# When setting any of these variables, check to see if a corresponding
61# variable is present in config.build; if so, you will likely want to 
62# set it in both places.
63
