22132718Skan# This is the GCC host-specific configuration file
23132718Skan# where a configuration type is mapped to different system-specific
24132718Skan# definitions and files.  This is invoked by the autoconf-generated
25132718Skan# configure script.  Putting it in a separate shell file lets us skip
26132718Skan# running autoconf when modifying host-specific information.
27132718Skan
28132718Skan# This file switches on the shell variable ${host}.  As much of this as
29132718Skan# is reasonable should be replaced with autoconf tests in the future.

31132718Skan# This file sets the following shell variables for use by the
32132718Skan# autoconf-generated configure script:
33132718Skan#
34132718Skan#  host_xm_file         List of files to include when compiling for the
35132718Skan#                       host machine.
36132718Skan#
37132718Skan#  host_xm_defines      List of macros to define when compiling for the
38132718Skan#                       host machine.
39132718Skan#
40132718Skan#  host_xmake_file      List of host-specific makefile-fragments.
41132718Skan#
42132718Skan#  host_exeext          Set to the suffix, if the host machine requires
43132718Skan#                       executables to have a file name suffix.
44132718Skan#
45132718Skan#  host_extra_objs      List of extra host-dependent objects that should
46132718Skan#                       be linked into the compiler proper.
47132718Skan#
48132718Skan#  host_extra_gcc_objs  List of extra host-dependent objects that should
49132718Skan#                       be linked into the gcc driver.
50132718Skan#
51132718Skan#  out_host_hook_obj    An object file that provides the host hooks.

54132718Skan# variable is present in config.build; if so, you will likely want to
