22 # This is the GCC target-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 target-specific information.
27
28 # This file switches on the shell variable ${target}, and also uses the
29 # following shell variables:
30 #
31 #  with_*               Various variables as set by configure.
32 #
33 #  enable_threads       Either the name, yes or no depending on whether
34 #                       threads support was requested.
35 #
36 #  default_use_cxa_atexit
37 #                       "no" by default, can be set to "yes" if a target
38 #                       wishes to use __cxa_atexit() by default if the
39 #                       $enable___cxa_atexit variable is not set.
40 #
41 #  gas_flag             Either yes or no depending on whether GNU as was
42 #                       requested.
43 #
44 #  gnu_ld_flag          Either yes or no depending on whether GNU ld was
45 #                       requested.
46
47 # This file sets the following shell variables for use by the
48 # autoconf-generated configure script:
49 #
50 #  cpu_type             The name of the cpu, if different from the first
51 #                       chunk of the canonical target name.
52 #
53 #  tm_defines           List of target macros to define for all compilations.
54 #
55 #  tm_file              A list of target macro files, if different from
56 #                       "$cpu_type/$cpu_type.h". Usually it's constructed
57 #                       per target in a way like this:
58 #                       tm_file="${tm_file} dbxelf.h elfos.h svr4.h ${cpu_type.h}/elf.h"
59 #                       Note that the preferred order is:
60 #                       - specific target header "${cpu_type}/${cpu_type.h}"
61 #                       - generic headers like dbxelf.h elfos.h, etc.
62 #                       - specializing target headers like ${cpu_type.h}/elf.h
63 #                       This helps to keep OS specific stuff out of the CPU
64 #                       defining header ${cpu_type}/${cpu_type.h}.
65 #
66 #  tm_p_file            Location of file with declarations for functions
67 #                       in $out_file.
68 #
69 #  out_file             The name of the machine description C support
70 #                       file, if different from "$cpu_type/$cpu_type.c".
71 #
72 #  md_file              The name of the machine-description file, if
73 #                       different from "$cpu_type/$cpu_type.md".
74 #
75 #  tmake_file           A list of machine-description-specific
76 #                       makefile-fragments, if different from
77 #                       "$cpu_type/t-$cpu_type".
78 #
79 #  extra_modes          The name of the file containing a list of extra
80 #                       machine modes, if necessary and different from
81 #                       "$cpu_type/$cpu_type-modes.def".
82 #
83 #  extra_objs           List of extra objects that should be linked into
84 #                       the compiler proper (cc1, cc1obj, cc1plus)
85 #                       depending on target.
86 #
87 #  extra_gcc_objs       List of extra objects that should be linked into
88 #                       the compiler driver (gcc) depending on target.
89 #
90 #  extra_headers        List of used header files from the directory
91 #                       config/${cpu_type}.
92 #
93 #  extra_passes         List of extra executables compiled for this target
94 #                       machine, used for compiling from source to object.
95 #
96 #  extra_parts          List of extra object files that should be compiled
97 #                       for this target machine.
98 #
99 #  extra_programs       Like extra_passes, but these are used when linking.
100 #
101 #  c_target_objs        List of extra target-dependent objects that be
102 #                       linked into the C compiler only.
103 #
104 #  cxx_target_objs      List of extra target-dependent objects that be
105 #                       linked into the C++ compiler only.
106 #
107 #  target_gtfiles       List of extra source files with type information.

125 #
126 #  gas                  Set to yes or no depending on whether the target
