 # 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.
