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 # When you change the cases in the OS or target switches, consider
29 # updating ../libgcc/config.host also.
30
31 # This file switches on the shell variable ${target}, and also uses the
32 # following shell variables:
33 #
34 #  with_*               Various variables as set by configure.
35 #
36 #  enable_threads       Either the name, yes or no depending on whether
37 #                       threads support was requested.
38 #
39 #  default_use_cxa_atexit
40 #                         The default value for the $enable___cxa_atexit
41 #                       variable.  enable___cxa_atexit needs to be set to
42 #                       "yes" for the correct operation of C++ destructors
43 #                       but it relies upon the presence of a non-standard C
44 #                       library function called __cxa_atexit.
45 #                         Since not all C libraries provide __cxa_atexit the
46 #                       default value of $default_use_cxa_atexit is set to
47 #                       "no" except for targets which are known to be OK.
48 #
49 #  gas_flag             Either yes or no depending on whether GNU as was
50 #                       requested.
51 #
52 #  gnu_ld_flag          Either yes or no depending on whether GNU ld was
53 #                       requested.
54
55 # This file sets the following shell variables for use by the
56 # autoconf-generated configure script:
57 #
58 #  cpu_type             The name of the cpu, if different from the first
59 #                       chunk of the canonical target name.
60 #
61 #  tm_defines           List of target macros to define for all compilations.
62 #
63 #  tm_file              A list of target macro files, if different from
64 #                       "$cpu_type/$cpu_type.h". Usually it's constructed
65 #                       per target in a way like this:
66 #                       tm_file="${tm_file} dbxelf.h elfos.h svr4.h ${cpu_type.h}/elf.h"
67 #                       Note that the preferred order is:
68 #                       - specific target header "${cpu_type}/${cpu_type.h}"
69 #                       - generic headers like dbxelf.h elfos.h, etc.
70 #                       - specializing target headers like ${cpu_type.h}/elf.h
71 #                       This helps to keep OS specific stuff out of the CPU
72 #                       defining header ${cpu_type}/${cpu_type.h}.
73 #
74 #  tm_p_file            Location of file with declarations for functions
75 #                       in $out_file.
76 #
77 #  out_file             The name of the machine description C support
78 #                       file, if different from "$cpu_type/$cpu_type.c".
79 #
80 #  md_file              The name of the machine-description file, if
81 #                       different from "$cpu_type/$cpu_type.md".
82 #
83 #  tmake_file           A list of machine-description-specific
84 #                       makefile-fragments, if different from
85 #                       "$cpu_type/t-$cpu_type".
86 #
87 #  extra_modes          The name of the file containing a list of extra
88 #                       machine modes, if necessary and different from
89 #                       "$cpu_type/$cpu_type-modes.def".
90 #
91 #  extra_objs           List of extra objects that should be linked into
92 #                       the compiler proper (cc1, cc1obj, cc1plus)
93 #                       depending on target.
94 #
95 #  extra_gcc_objs       List of extra objects that should be linked into
96 #                       the compiler driver (gcc) depending on target.
97 #
98 #  extra_headers        List of used header files from the directory
99 #                       config/${cpu_type}.
100 #
101 #  extra_passes         List of extra executables compiled for this target
102 #                       machine, used for compiling from source to object.
103 #
104 #  extra_parts          List of extra object files that should be compiled
105 #                       for this target machine.
106 #
107 #  extra_programs       Like extra_passes, but these are used when linking.
108 #
109 #  extra_options        List of target-dependent .opt files.
110 #
111 #  c_target_objs        List of extra target-dependent objects that be
112 #                       linked into the C compiler only.
113 #
114 #  cxx_target_objs      List of extra target-dependent objects that be
115 #                       linked into the C++ compiler only.

129 #
130 #  gdb_needs_out_file_path
