21 # This is the GCC target-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 target-specific information.
26
27 # When you change the cases in the OS or target switches, consider
28 # updating ../libgcc/config.host also.
29
30 # This file switches on the shell variable ${target}, and also uses the
31 # following shell variables:
32 #
33 #  with_*               Various variables as set by configure.
34 #
35 #  enable_threads       Either the name, yes or no depending on whether
36 #                       threads support was requested.
37 #
38 #  default_use_cxa_atexit
39 #                         The default value for the $enable___cxa_atexit
40 #                       variable.  enable___cxa_atexit needs to be set to
41 #                       "yes" for the correct operation of C++ destructors
42 #                       but it relies upon the presence of a non-standard C
43 #                       library function called __cxa_atexit.
44 #                         Since not all C libraries provide __cxa_atexit the
45 #                       default value of $default_use_cxa_atexit is set to
46 #                       "no" except for targets which are known to be OK.
47 #
48 #  gas_flag             Either yes or no depending on whether GNU as was
49 #                       requested.
50 #
51 #  gnu_ld_flag          Either yes or no depending on whether GNU ld was
52 #                       requested.
53
54 # This file sets the following shell variables for use by the
55 # autoconf-generated configure script:
56 #
57 #  cpu_type             The name of the cpu, if different from the first
58 #                       chunk of the canonical target name.
59 #
60 #  tm_defines           List of target macros to define for all compilations.
61 #
62 #  tm_file              A list of target macro files, if different from
63 #                       "$cpu_type/$cpu_type.h". Usually it's constructed
64 #                       per target in a way like this:
65 #                       tm_file="${tm_file} dbxelf.h elfos.h svr4.h ${cpu_type.h}/elf.h"
66 #                       Note that the preferred order is:
67 #                       - specific target header "${cpu_type}/${cpu_type.h}"
68 #                       - generic headers like dbxelf.h elfos.h, etc.
69 #                       - specializing target headers like ${cpu_type.h}/elf.h
70 #                       This helps to keep OS specific stuff out of the CPU
71 #                       defining header ${cpu_type}/${cpu_type.h}.
72 #
73 #                       It is possible to include automatically-generated
74 #                       build-directory files by prefixing them with "./".
75 #                       All other files should relative to $srcdir/config.
76 #
77 #  tm_p_file            Location of file with declarations for functions
78 #                       in $out_file.
79 #

81 #                       file, if different from "$cpu_type/$cpu_type.c".
82 #
83 #  md_file              The name of the machine-description file, if
84 #                       different from "$cpu_type/$cpu_type.md".
85 #
86 #  tmake_file           A list of machine-description-specific
87 #                       makefile-fragments, if different from
88 #                       "$cpu_type/t-$cpu_type".
89 #
90 #  extra_modes          The name of the file containing a list of extra
91 #                       machine modes, if necessary and different from
92 #                       "$cpu_type/$cpu_type-modes.def".
93 #
94 #  extra_objs           List of extra objects that should be linked into
95 #                       the compiler proper (cc1, cc1obj, cc1plus)
96 #                       depending on target.
97 #
98 #  extra_gcc_objs       List of extra objects that should be linked into
99 #                       the compiler driver (gcc) depending on target.
100 #
101 #  extra_headers        List of used header files from the directory
102 #                       config/${cpu_type}.
103 #
104 #  use_gcc_tgmath       If set, add tgmath.h to the list of used header
105 #                       files.
106 #
107 #  use_gcc_stdint       If "wrap", install a version of stdint.h that
108 #                       wraps the system's copy for hosted compilations;
109 #                       if "provide", provide a version of systems without
110 #                       such a system header; otherwise "none", do not
111 #                       provide such a header at all.
112 #
113 #  extra_passes         List of extra executables compiled for this target
114 #                       machine, used for compiling from source to object.
115 #
116 #  extra_parts          List of extra object files that should be compiled
117 #                       for this target machine.
