# 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.
|
||
|
|
|
||
|
|
# 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.
|
