+# Configuration subroutine to validate and canonicalize a configuration type.

+# If it is invalid, we print an error message on stderr and exit with code 1.
+# Otherwise, we print the canonical config type on stdout and succeed.

+# a failure to support a valid configuration from a meaningless
+# configuration.

+# The goal of this file is to map all the various variations of a given

+#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# or in some cases, the newer four-part form:
+#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM

+# 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.
+
+# When you change the cases in the OS or target switches, consider
+# updating ../libgcc/config.host also.
+
+# This file switches on the shell variable ${target}, and also uses the
+# following shell variables:
+#
+#  with_*		Various variables as set by configure.
+#
+#  enable_threads	Either the name, yes or no depending on whether
+#			threads support was requested.
+#
+#  default_use_cxa_atexit
+#			  The default value for the $enable___cxa_atexit
+#			variable.  enable___cxa_atexit needs to be set to
+#			"yes" for the correct operation of C++ destructors
+#			but it relies upon the presence of a non-standard C
+#			library	function called	__cxa_atexit.
+#			  Since not all C libraries provide __cxa_atexit the
+#			default value of $default_use_cxa_atexit is set to
+#			"no" except for targets which are known to be OK.
+#
+#  default_gnu_indirect_function
+#                       The default value for the $enable_gnu_indirect_function
+#                       variable.  enable_gnu_indirect_function relies
+#			upon the presence of a non-standard gnu ifunc support
+#			in the assembler, linker and dynamic linker.
+#			Since not all libraries provide the dynamic linking
+#			support, the default value of
+#			$default_gnu_indirect_function is set to
+#			"no" except for targets which are known to be OK.
+#
+#  gas_flag		Either yes or no depending on whether GNU as was
+#			requested.
+#
+#  gnu_ld_flag		Either yes or no depending on whether GNU ld was
+#			requested.
+
+# This file sets the following shell variables for use by the
+# autoconf-generated configure script:
+#
+#  cpu_type		The name of the cpu, if different from the first
+#			chunk of the canonical target name.
+#
+#  tm_defines		List of target macros to define for all compilations.
+#
+#  tm_file		A list of target macro files, if different from
+#			"$cpu_type/$cpu_type.h". Usually it's constructed
+#			per target in a way like this:
+#			tm_file="${tm_file} dbxelf.h elfos.h ${cpu_type.h}/elf.h"
+#			Note that the preferred order is:
+#			- specific target header "${cpu_type}/${cpu_type.h}"
+#			- generic headers like dbxelf.h elfos.h, 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}.
+#
+#			It is possible to include automatically-generated
+#			build-directory files by prefixing them with "./".
+#			All other files should relative to $srcdir/config.
+#
+#  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/$cpu_type.c".
+#
+#  common_out_file	The name of the source file for code shared between
+#			the compiler proper and the driver.
+#
+#  md_file		The name of the machine-description file, if
+#			different from "$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}.
+#
+#  user_headers_inc_next_pre
+#			List of header file names of internal gcc header
+#			files, which should be prefixed by an include_next.
+#  user_headers_inc_next_post
+#			List of header file names of internal gcc header
+#			files, which should be postfixed by an include_next.
+#  use_gcc_tgmath	If set, add tgmath.h to the list of used header
+#			files.
+#
+#  use_gcc_stdint	If "wrap", install a version of stdint.h that
+#			wraps the system's copy for hosted compilations;
+#			if "provide", provide a version of systems without
+#			such a system header; otherwise "none", do not
+#			provide such a header at all.
+#
+#  extra_programs	List of extra executables compiled for this target
+#			machine, used when linking.
+#
+#  extra_options	List of target-dependent .opt files.
+#
+#  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.
+#
+#  fortran_target_objs	List of extra target-dependent objects that be
+#			linked into the fortran 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.
+#
+#  configure_default_options
+#			Set to an initializer for configure_default_options
+#			in configargs.h, based on --with-cpu et cetera.
+#
+#  native_system_header_dir
+#			Where system header files are found for this
+#			target.  This defaults to /usr/include.  If
+#			the --with-sysroot configure option or the
+#			--sysroot command line option is used this
+#			will be relative to the sysroot.
+# target_type_format_char 
+# 			The default character to be used for formatting

+# This is the libgcc 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 bears an obvious resemblance to gcc/config.gcc.  The cases
+# should be kept similar, to ease moving library-specific settings
+# from config.gcc to this file.  That is also why tmake_file is
+# left as tmake_file, rather than hmake_file, even though this library
+# switches on ${host}.
+
+# This file switches on the shell variable ${host}, and also uses the
+# following shell variables:
+#
+#  with_*		Various variables as set by configure.
+
+# This file sets the following shell variables for use by the
+# autoconf-generated configure script:
+#
+#  asm_hidden_op	The assembler pseudo-op to use for hide
+#			lists for object files implemented in
+#			assembly (with -fvisibility=hidden for C).
+#			The default is ".hidden".
+#  cpu_type		The name of the cpu, if different from the first
+#			chunk of the canonical host name.
+#  enable_execute_stack The name of a source file implementing
+#			__enable_execute_stack.
+#  extra_parts		List of extra object files that should be compiled
+#			for this target machine.  This may be overridden
+#			by setting EXTRA_PARTS in a tmake_file fragment.
+#			If either is set, EXTRA_PARTS and
+#			EXTRA_MULTILIB_PARTS inherited from the GCC
+#			subdirectory will be ignored.
+#  md_unwind_header	The name of a header file defining
+#			MD_FALLBACK_FRAME_STATE_FOR.
+#  sfp_machine_header	The name of a sfp-machine.h header file for soft-fp.
+#  			Defaults to "$cpu_type/sfp-machine.h" if it exists,
+#			no-sfp-machine.h otherwise.
+#  tmake_file		A list of machine-description-specific
+#			makefile fragments.
+#  tm_defines		List of target macros to define for all compilations.
+#  tm_file		A list of target macro files used only for code
+#			built for the target, not the host.  These files
+#			are relative to $srcdir/config and must not have
+#			the same names as files in $srcdir/../gcc/config.
+#  unwind_header	The name of the header file declaring the unwind
+#			runtime interface routines.
