+# 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 ${host}, and also uses the
+# following shell variables:
+#
+#  with_*		Various variables as set by configure.
+
+# This file sets the following shell variables for use by the
+# autoconf-generated configure script:
+#
+#  asm_hidden_op	The assembler pseudo-op to use for hide
+#			lists for object files implemented in
+#			assembly (with -fvisibility=hidden for C).
+#			The default is ".hidden".
+#  cpu_type		The name of the cpu, if different from the first
+#			chunk of the canonical host name.
+#  extra_parts		List of extra object files that should be compiled
+#			for this target machine.  This may be overridden
+#			by setting EXTRA_PARTS in a tmake_file fragment.
+#			If either is set, EXTRA_PARTS and
+#			EXTRA_MULTILIB_PARTS inherited from the GCC
+#			subdirectory will be ignored.
+#  tmake_file		A list of machine-description-specific
+#			makefile-fragments, if different from
+#			"$cpu_type/t-$cpu_type".
