21 # This is the libgcc host-specific configuration file
22 # where a configuration type is mapped to different system-specific
23 # definitions and files. This is invoked by the autoconf-generated
24 # configure script. Putting it in a separate shell file lets us skip
25 # running autoconf when modifying host-specific information.
27 # This file bears an obvious resemblance to gcc/config.gcc. The cases
28 # should be kept similar, to ease moving library-specific settings
29 # from config.gcc to this file. That is also why tmake_file is
30 # left as tmake_file, rather than hmake_file, even though this library
31 # switches on ${host}.
33 # This file switches on the shell variable ${host}, and also uses the
34 # following shell variables:
36 # with_* Various variables as set by configure.
38 # This file sets the following shell variables for use by the
39 # autoconf-generated configure script:
41 # asm_hidden_op The assembler pseudo-op to use for hide
42 # lists for object files implemented in
43 # assembly (with -fvisibility=hidden for C).
44 # The default is ".hidden".
45 # cpu_type The name of the cpu, if different from the first
46 # chunk of the canonical host name.
47 # enable_execute_stack The name of a source file implementing
48 # __enable_execute_stack.
49 # extra_parts List of extra object files that should be compiled
50 # for this target machine. This may be overridden
51 # by setting EXTRA_PARTS in a tmake_file fragment.
52 # If either is set, EXTRA_PARTS and
53 # EXTRA_MULTILIB_PARTS inherited from the GCC
54 # subdirectory will be ignored.
55 # md_unwind_header The name of a header file defining
56 # MD_FALLBACK_FRAME_STATE_FOR.
57 # tmake_file A list of machine-description-specific
58 # makefile-fragments, if different from
59 # "$cpu_type/t-$cpu_type".
65 md_unwind_header=no-unwind.h
