# 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'.

# 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.
