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 #  default_gnu_indirect_function
49 #                       The default value for the $enable_gnu_indirect_function
50 #                       variable.  enable_gnu_indirect_function relies
51 #                       upon the presence of a non-standard gnu ifunc support
52 #                       in the assembler, linker and dynamic linker.
53 #                       Since not all libraries provide the dynamic linking
54 #                       support, the default value of
55 #                       $default_gnu_indirect_function is set to
56 #                       "no" except for targets which are known to be OK.
57 #
58 #  gas_flag             Either yes or no depending on whether GNU as was
59 #                       requested.
60 #
61 #  gnu_ld_flag          Either yes or no depending on whether GNU ld was
62 #                       requested.
63
64 # This file sets the following shell variables for use by the
65 # autoconf-generated configure script:
66 #
67 #  cpu_type             The name of the cpu, if different from the first
68 #                       chunk of the canonical target name.
69 #
70 #  tm_defines           List of target macros to define for all compilations.
71 #
72 #  tm_file              A list of target macro files, if different from
73 #                       "$cpu_type/$cpu_type.h". Usually it's constructed
74 #                       per target in a way like this:
75 #                       tm_file="${tm_file} dbxelf.h elfos.h ${cpu_type.h}/elf.h"
76 #                       Note that the preferred order is:
77 #                       - specific target header "${cpu_type}/${cpu_type.h}"
78 #                       - generic headers like dbxelf.h elfos.h, etc.
79 #                       - specializing target headers like ${cpu_type.h}/elf.h
80 #                       This helps to keep OS specific stuff out of the CPU
81 #                       defining header ${cpu_type}/${cpu_type.h}.
82 #
83 #                       It is possible to include automatically-generated
84 #                       build-directory files by prefixing them with "./".
85 #                       All other files should relative to $srcdir/config.
86 #

88 #                       in $out_file.
89 #

97 #                       different from "$cpu_type/$cpu_type.md".
98 #
99 #  tmake_file           A list of machine-description-specific

102 #
103 #  extra_modes          The name of the file containing a list of extra
104 #                       machine modes, if necessary and different from
105 #                       "$cpu_type/$cpu_type-modes.def".
106 #
107 #  extra_objs           List of extra objects that should be linked into
108 #                       the compiler proper (cc1, cc1obj, cc1plus)

110 #

120 #  user_headers_inc_next_post
121 #                       List of header file names of internal gcc header
122 #                       files, which should be postfixed by an include_next.

124 #                       files.
125 #
126 #  use_gcc_stdint       If "wrap", install a version of stdint.h that
