++# 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.
