If not see #. # This is the GCC host-specific configuration file # where a configuration type is mapped to different system-specific # definitions and files. This is invoked by the autoconf-generated # configure script. Putting it in a separate shell file lets us skip # running autoconf when modifying host-specific information. # This file switches on the shell variable ${host}. As much of this as # is reasonable should be replaced with autoconf tests in the future. # This file sets the following shell variables for use by the # autoconf-generated configure script: # # host_xm_file List of files to include when compiling for the # host machine. # # host_xm_defines List of macros to define when compiling for the # host machine. # # host_xmake_file List of host-specific makefile-fragments. # # host_exeext Set to the suffix, if the host machine requires # executables to have a file name suffix. # # host_extra_objs List of extra host-dependent objects that should # be linked into the compiler proper. # # host_extra_gcc_objs List of extra host-dependent objects that should # be linked into the gcc driver. # # out_host_hook_obj An object file that provides the host hooks. # # host_can_use_collect2 Set to yes normally; to no if the host cannot # link or otherwise use collect2 # # use_long_long_for_widest_fast_int Set this to 'yes' if 'long long' # (or '__int64') is wider than 'long' but still # efficeiently supported by the host hardware. # Only affects compile speed. Default is 'no'. # # host_lto_plugin_soname Set this to the name to which the LTO linker # plugin gets compiled on this host, if it is # different from the default "liblto_plugin.so". # When setting any of these variables, check to see if a corresponding # variable is present in config.build; if so, you will likely want to # set it in both places. # Default settings. host_xm_file= host_xm_defines= host_xmake_file= host_exeext= host_extra_objs= host_extra_gcc_objs= out_host_hook_obj=host-default.o host_can_use_collect2=yes use_long_long_for_widest_fast_int=no host_lto_plugin_soname=liblto_plugin.so host_function_reordering_plugin_soname=libfunction_reordering_plugin.so # Unsupported hosts list.
