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

87 #                       in $out_file.

93 #                       the compiler proper and the driver.
95 #  md_file              The name of the machine-description file, if
96 #                       different from "$cpu_type/$cpu_type.md".
98 #  tmake_file           A list of machine-description-specific
99 #                       makefile-fragments, if different from
100 #                       "$cpu_type/t-$cpu_type".
102 #  extra_modes          The name of the file containing a list of extra
103 #                       machine modes, if necessary and different from
104 #                       "$cpu_type/$cpu_type-modes.def".
106 #  extra_objs           List of extra objects that should be linked into
107 #                       the compiler proper (cc1, cc1obj, cc1plus)
108 #                       depending on target.
110 #  extra_gcc_objs       List of extra objects that should be linked into
111 #                       the compiler driver (gcc) depending on target.
113 #  extra_headers        List of used header files from the directory
114 #                       config/${cpu_type}.

120 #                       List of header file names of internal gcc header
121 #                       files, which should be postfixed by an include_next.
122 #  use_gcc_tgmath       If set, add tgmath.h to the list of used header
123 #                       files.
125 #  use_gcc_stdint       If "wrap", install a version of stdint.h that
126 #                       wraps the system's copy for hosted compilations;
127 #                       if "provide", provide a version of systems without
128 #                       such a system header; otherwise "none", do not
