| # 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. |
