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

126 #
127 #  gdb_needs_out_file_path
128 #                       Set to yes if gdb needs a dir command with
129 #                       `dirname $out_file`.
130 #
131 #  thread_file          Set to control which thread package to use.
