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.
28 # When you change the cases in the OS or target switches, consider
29 # updating ../libgcc/config.host also.
31 # This file switches on the shell variable ${target}, and also uses the
32 # following shell variables:
34 #  with_*               Various variables as set by configure.
36 #  enable_threads       Either the name, yes or no depending on whether
37 #                       threads support was requested.
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 $default_use_cxa_atexit is set to
47 #                       "no" except for targets which are known to be OK.
49 #  gas_flag             Either yes or no depending on whether GNU as was
50 #                       requested.
52 #  gnu_ld_flag          Either yes or no depending on whether GNU ld was
53 #                       requested.
55 # This file sets the following shell variables for use by the
56 # autoconf-generated configure script:
58 #  cpu_type             The name of the cpu, if different from the first
59 #                       chunk of the canonical target name.
61 #  tm_defines           List of target macros to define for all compilations.
63 #  tm_file              A list of target macro files, if different from
64 #                       "$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}.
74 #  tm_p_file            Location of file with declarations for functions
75 #                       in $out_file.
77 #  out_file             The name of the machine description C support
78 #                       file, if different from "$cpu_type/$cpu_type.c".
80 #  md_file              The name of the machine-description file, if
81 #                       different from "$cpu_type/$cpu_type.md".
83 #  tmake_file           A list of machine-description-specific
84 #                       makefile-fragments, if different from
85 #                       "$cpu_type/t-$cpu_type".
87 #  extra_modes          The name of the file containing a list of extra
88 #                       machine modes, if necessary and different from
89 #                       "$cpu_type/$cpu_type-modes.def".
91 #  extra_objs           List of extra objects that should be linked into
92 #                       the compiler proper (cc1, cc1obj, cc1plus)
93 #                       depending on target.
95 #  extra_gcc_objs       List of extra objects that should be linked into
96 #                       the compiler driver (gcc) depending on target.
98 #  extra_headers        List of used header files from the directory
99 #                       config/${cpu_type}.
101 #  extra_passes         List of extra executables compiled for this target
102 #                       machine, used for compiling from source to object.
104 #  extra_parts          List of extra object files that should be compiled
105 #                       for this target machine.
107 #  extra_programs       Like extra_passes, but these are used when linking.
109 #  extra_options        List of target-dependent .opt files.
111 #  c_target_objs        List of extra target-dependent objects that be
112 #                       linked into the C compiler only.
114 #  cxx_target_objs      List of extra target-dependent objects that be
115 #                       linked into the C++ compiler only.
117 #  target_gtfiles       List of extra source files with type information.
119 #  xm_defines           List of macros to define when compiling for the
120 #                       target machine.
122 #  xm_file              List of files to include when compiling for the
123 #                       target machine.
125 #  use_collect2         Set to yes or no, depending on whether collect2
126 #                       will be used.
128 #  target_cpu_default   Set to override the default target model.
130 #  gdb_needs_out_file_path
131 #                       Set to yes if gdb needs a dir command with
132 #                       `dirname $out_file`.
134 #  thread_file          Set to control which thread package to use.
136 #  gas                  Set to yes or no depending on whether the target
137 #                       system normally uses GNU as.
139 #  need_64bit_hwint     Set to yes if HOST_WIDE_INT must be 64 bits wide
140 #                       for this target.  This is true iff this target
141 #                       supports "long" or "wchar_t" wider than 32 bits.
143 #  configure_default_options
144 #                       Set to an initializer for configure_default_options
145 #                       in configargs.h, based on --with-cpu et cetera.
147 #  use_fixproto         Set to "yes" if fixproto should be run normally,
148 #                       "no" if fixproto should never be run.
150 # The following variables are used in each case-construct to build up the
151 # outgoing variables:
