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