22 # This is the libgcc host-specific configuration file
23 # where a configuration type is mapped to different system-specific
24 # definitions and files. This is invoked by the autoconf-generated
25 # configure script. Putting it in a separate shell file lets us skip
26 # running autoconf when modifying host-specific information.
28 # This file bears an obvious resemblance to gcc/config.gcc. The cases
29 # should be kept similar, to ease moving library-specific settings
30 # from config.gcc to this file. That is also why tmake_file is
31 # left as tmake_file, rather than hmake_file, even though this library
32 # switches on ${host}.
34 # This file switches on the shell variable ${host}, and also uses the
35 # following shell variables:
37 # with_* Various variables as set by configure.
39 # This file sets the following shell variables for use by the
40 # autoconf-generated configure script:
42 # asm_hidden_op The assembler pseudo-op to use for hide
43 # lists for object files implemented in
44 # assembly (with -fvisibility=hidden for C).
45 # The default is ".hidden".
46 # cpu_type The name of the cpu, if different from the first
47 # chunk of the canonical host name.
48 # extra_parts List of extra object files that should be compiled
49 # for this target machine. This may be overridden
50 # by setting EXTRA_PARTS in a tmake_file fragment.
51 # If either is set, EXTRA_PARTS and
52 # EXTRA_MULTILIB_PARTS inherited from the GCC
53 # subdirectory will be ignored.
54 # tmake_file A list of machine-description-specific
55 # makefile-fragments, if different from
56 # "$cpu_type/t-$cpu_type".
62 # Set default cpu_type so it can be updated in each machine entry.
