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
|

27 # This file switches on the shell variable ${host}. As much of this as

|
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.
|
