20# This is the libgcc host-specific configuration file
21# where a configuration type is mapped to different system-specific
22# definitions and files.  This is invoked by the autoconf-generated
23# configure script.  Putting it in a separate shell file lets us skip
24# running autoconf when modifying host-specific information.
25
26# This file bears an obvious resemblance to gcc/config.gcc.  The cases
27# should be kept similar, to ease moving library-specific settings
28# from config.gcc to this file.  That is also why tmake_file is
29# left as tmake_file, rather than hmake_file, even though this library
30# switches on ${host}.
31
32# This file switches on the shell variable ${host}, and also uses the
33# following shell variables:
34#
35#  with_*		Various variables as set by configure.
36
37# This file sets the following shell variables for use by the
38# autoconf-generated configure script:
39#
40#  asm_hidden_op	The assembler pseudo-op to use for hide
41#			lists for object files implemented in
42#			assembly (with -fvisibility=hidden for C).
43#			The default is ".hidden".
44#  cpu_type		The name of the cpu, if different from the first
45#			chunk of the canonical host name.
46#  enable_execute_stack The name of a source file implementing
47#			__enable_execute_stack.
48#  extra_parts		List of extra object files that should be compiled
49#			for this target machine.  This may be overridden
50#			by setting EXTRA_PARTS in a tmake_file fragment.
51#			If either is set, EXTRA_PARTS and
52#			EXTRA_MULTILIB_PARTS inherited from the GCC
53#			subdirectory will be ignored.
54#  md_unwind_header	The name of a header file defining
55#			MD_FALLBACK_FRAME_STATE_FOR.
56#  sfp_machine_header	The name of a sfp-machine.h header file for soft-fp.
57#  			Defaults to "$cpu_type/sfp-machine.h" if it exists,
58#			no-sfp-machine.h otherwise.
59#  tmake_file		A list of machine-description-specific
60#			makefile fragments.
61#  tm_defines		List of target macros to define for all compilations.
62#  tm_file		A list of target macro files used only for code
63#			built for the target, not the host.  These files
64#			are relative to $srcdir/config and must not have
65#			the same names as files in $srcdir/../gcc/config.
66#  unwind_header	The name of the header file declaring the unwind
67#			runtime interface routines.
