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.
