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.
26
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.
29
30 # This file sets the following shell variables for use by the
31 # autoconf-generated configure script:
32 #
33 # host_xm_file List of files to include when compiling for the
34 # host machine.
35 #
36 # host_xm_defines List of macros to define when compiling for the
37 # host machine.
38 #
39 # host_xmake_file List of host-specific makefile-fragments.
40 #
41 # host_exeext Set to the suffix, if the host machine requires
42 # executables to have a file name suffix.
43 #
44 # host_extra_objs List of extra host-dependent objects that should
45 # be linked into the compiler proper.
46 #
47 # host_extra_gcc_objs List of extra host-dependent objects that should
48 # be linked into the gcc driver.
49 #
50 # out_host_hook_obj An object file that provides the host hooks.
51 #
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'.
58
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.
62
63 # Default settings.
