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.
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}.
32 # This file switches on the shell variable ${host}, and also uses the
33 # following shell variables:
35 #  with_*               Various variables as set by configure.
37 # This file sets the following shell variables for use by the
38 # autoconf-generated configure script:
40 #  asm_hidden_op        The assembler pseudo-op to use for hide
41 #                       lists for object files implemented in
42 #                       assembly (with -fvisibility=hidden for C).
43 #                       The default is ".hidden".
44 #  cpu_type             The name of the cpu, if different from the first
45 #                       chunk of the canonical host name.
46 #  enable_execute_stack The name of a source file implementing
47 #                       __enable_execute_stack.
48 #  extra_parts          List of extra object files that should be compiled
49 #                       for this target machine.  This may be overridden
50 #                       by setting EXTRA_PARTS in a tmake_file fragment.
51 #                       If either is set, EXTRA_PARTS and
52 #                       EXTRA_MULTILIB_PARTS inherited from the GCC
53 #                       subdirectory will be ignored.
54 #  md_unwind_header     The name of a header file defining
55 #                       MD_FALLBACK_FRAME_STATE_FOR.
56 #  sfp_machine_header   The name of a sfp-machine.h header file for soft-fp.
57 #                       Defaults to "$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.
