21 # This is the GCC host-specific configuration file
22 # where a configuration type is mapped to different system-specific
23 # definitions and files.  This is invoked by the autoconf-generated
24 # configure script.  Putting it in a separate shell file lets us skip
25 # running autoconf when modifying host-specific information.
27 # This file switches on the shell variable ${host}.  As much of this as
28 # is reasonable should be replaced with autoconf tests in the future.
30 # This file sets the following shell variables for use by the
31 # autoconf-generated configure script:
33 #  host_xm_file         List of files to include when compiling for the
34 #                       host machine.
36 #  host_xm_defines      List of macros to define when compiling for the
37 #                       host machine.
39 #  host_xmake_file      List of host-specific makefile-fragments.
41 #  host_exeext          Set to the suffix, if the host machine requires
42 #                       executables to have a file name suffix.
44 #  host_extra_objs      List of extra host-dependent objects that should
45 #                       be linked into the compiler proper.
47 #  host_extra_gcc_objs  List of extra host-dependent objects that should
48 #                       be linked into the gcc driver.
50 #  out_host_hook_obj    An object file that provides the host hooks.
52 #  host_can_use_collect2 Set to yes normally; to no if the host cannot
53 #                       link or otherwise use collect2
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'.
59 # When setting any of these variables, check to see if a corresponding
60 # variable is present in config.build; if so, you will likely want to 
61 # set it in both places.
