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. | |
c38f02df ILT |
51 | # |
52 | # host_can_use_collect2 Set to yes normally; to no if the host cannot | |
53 | # link or otherwise use collect2 | |
1cd0b716 | 54 | # |
99fa8911 AP |
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'. | |
1cd0b716 DK |
59 | # |
60 | # host_lto_plugin_soname Set this to the name to which the LTO linker | |
61 | # plugin gets compiled on this host, if it is | |
62 | # different from the default "liblto_plugin.so". | |
