+# 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.
