+# This is the GCC target-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 target-specific information.
+
+# This file switches on the shell variable ${target}, and also uses the
+# following shell variables:
+#
+#  with_*		Various variables as set by configure.
+#
+#  enable_threads_flag	Either the name, yes or no depending on whether
+#			threads support was requested.
+#
+#  default_use_cxa_atexit
+#			"no" by default, can be set to "yes" if a target
+#			wishes to use __cxa_atexit() by default if the
+#			$enable___cxa_atexit variable is not set.
+#
+#  gas_flag		Either yes or no depending on whether GNU as was
+#			requested.
+#
+#  gnu_ld_flag		Either yes or no depending on whether GNU ld was
+#			requested.
+
+# This file sets the following shell variables for use by the
+# autoconf-generated configure script:
+#
+#  cpu_type		The name of the cpu, if different from the first
+#			chunk of the canonical target name.
+#
+#  tm_defines		List of target macros to define for all compilations.
+#
+#  tm_file		A list of target macro files, if different from
+#			"$cpu_type/$cpu_type.h". Usually it's constructed
+#			per target in a way like this:
+#			tm_file="${tm_file} dbxelf.h elfos.h svr4.h ${cpu_type.h}/elf.h"
+#			Note that the preferred order is:
+#			- specific target header "${cpu_type}/${cpu_type.h}"
+#			- generic headers like dbxelf.h elfos.h, netware.h, etc.
+#			- specializing target headers like ${cpu_type.h}/elf.h
+#			This helps to keep OS specific stuff out of the CPU
+#			defining header ${cpu_type}/${cpu_type.h}.
+#
+#  tm_p_file		Location of file with declarations for functions
+#			in $out_file.
+#
+#  out_file		The name of the machine description C support
+#			file, if different from "$cpu_type/$cpu_type.c".
+#
+#  md_file		The name of the machine-description file, if
+#			different from "$cpu_type/$cpu_type.md".
+#
+#  tmake_file		A list of machine-description-specific
+#			makefile-fragments, if different from
+#			"$cpu_type/t-$cpu_type".
+#
+#  extra_modes          The name of the file containing a list of extra
+#                       machine modes, if necessary and different from
+#                       "$cpu_type/$cpu_type-modes.def".
+#
+#  extra_objs		List of extra objects that should be linked into
+#			the compiler proper (cc1, cc1obj, cc1plus)
+#			depending on target.
+#
+#  extra_gcc_objs	List of extra objects that should be linked into
+#			the compiler driver (gcc) depending on target.
+#
+#  extra_headers	List of used header files from the directory
+#			config/${cpu_type}.
+#
+#  extra_passes		List of extra executables compiled for this target
+#			machine, used for compiling from source to object.
+#
+#  extra_parts		List of extra object files that should be compiled
+#			for this target machine.
+#
+#  extra_programs	Like extra_passes, but these are used when linking.
+#
+#  c_target_objs	List of extra target-dependent objects that be
+#			linked into the C compiler only.
+#
+#  cxx_target_objs	List of extra target-dependent objects that be
+#			linked into the C++ compiler only.
+#
+#  target_gtfiles       List of extra source files with type information.
+#
+#  xm_defines		List of macros to define when compiling for the
+#			target machine.
+#
+#  xm_file		List of files to include when compiling for the
+#			target machine.
+#
+#  use_collect2		Set to yes or no, depending on whether collect2
+#			will be used.
+#
+#  target_cpu_default	Set to override the default target model.
+#
+#  gdb_needs_out_file_path
+#			Set to yes if gdb needs a dir command with
+#			`dirname $out_file`.
+#
+#  thread_file		Set to control which thread package to use.
+#
+#  gas			Set to yes or no depending on whether the target
+#			system normally uses GNU as.
+#
+#  need_64bit_hwint	Set to yes if HOST_WIDE_INT must be 64 bits wide
+#			for this target.  This is true iff
+#			MAX_LONG_TYPE_SIZE is 64.  (The code which
+#			determines the underlying integral type for
+#			HOST_WIDE_INT cannot see the definition of
+#			MAX_LONG_TYPE_SIZE.)
+#
+#  configure_default_options
+#			Set to an initializer for configure_default_options
+#			in configargs.h, based on --with-cpu et cetera.
+#
+#  use_fixproto		Set to "yes" if fixproto should be run normally,
+#			"no" if fixproto should never be run.
+
+# The following variables are used in each case-construct to build up the
+# outgoing variables:
+#
+#  gnu_ld		Set to yes or no depending on whether the target
