  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 ${machine}, and also uses the
  29 # following shell variables:
  30 #
  31 #  with_*               Various variables as set by configure.
  32 #
  33 #  enable_threads_flag  Either the name, yes or no depending on whether
  34 #                       threads support was requested.
  35 #
  36 #  default_use_cxa_atexit
  37 #                       "no" by default, can be set to "yes" if a target
  38 #                       wishes to use __cxa_atexit() by default if the
  39 #                       $enable___cxa_atexit variable is not set.
  40 #
  41 #  gas_flag             Either yes or no depending on whether GNU as was
  42 #                       requested.
  43 #
  44 #  gnu_ld_flag          Either yes or no depending on whether GNU ld was
  45 #                       requested.
  46
  47 # This file sets the following shell variables for use by the
  48 # autoconf-generated configure script:
  49 #
  50 #  cpu_type             The name of the cpu, if different from machine.
  51 #
  52 #  tm_defines           List of target macros to define for all compilations.
  53 #
  54 #  tm_file              A list of target macro files, if different from
  55 #                       "$cpu_type/$cpu_type.h". Usually it's constructed
  56 #                       per target in a way like this:
  57 #                       tm_file="${tm_file} dbxelf.h elfos.h svr4.h ${cpu_type.h}/elf.h"
  58 #                       Note that the preferred order is:
  59 #                       - specific target header "${cpu_type}/${cpu_type.h}"
  60 #                       - generic headers like dbxelf.h elfos.h, netware.h, etc.
  61 #                       - specializing target headers like ${cpu_type.h}/elf.h
  62 #                       This helps to keep OS specific stuff out of the CPU
  63 #                       defining header ${cpu_type}/${cpu_type.h}.
  64 #
  65 #  tm_p_file            Location of file with declarations for functions
  66 #                       in $out_file.
  67 #
  68 #  out_file             The name of the machine description C support
  69 #                       file, if different from "$cpu_type/$cpu_type.c".

  71 #  md_file              The name of the machine-description file, if
  72 #                       different from "$cpu_type/$cpu_type.md".
  73 #
  74 #  tmake_file           A list of machine-description-specific
  75 #                       makefile-fragments, if different from
  76 #                       "$cpu_type/t-$cpu_type".
  77 #
  78 #  extra_modes          The name of the file containing a list of extra
  79 #                       machine modes, if necessary and different from
  80 #                       "$cpu_type/$cpu_type-modes.def".
  81 #
  82 #  extra_objs           List of extra objects that should be linked into
  83 #                       the compiler proper (cc1, cc1obj, cc1plus)
  84 #                       depending on target.
  85 #
  86 #  extra_headers        List of used header files from the directory
  87 #                       config/${cpu_type}.
  88 #
  89 #  extra_passes         List of extra executables compiled for this target
  90 #                       machine, used for compiling from source to object.
  91 #
  92 #  extra_parts          List of extra object files that should be compiled
  93 #                       for this target machine.
  94 #
  95 #  extra_programs       Like extra_passes, but these are used when linking.
  96 #
  97 #  c_target_objs        List of extra target-dependent objects that be
  98 #                       linked into the C compiler only.
  99 #
 100 #  cxx_target_objs      List of extra target-dependent objects that be
 101 #                       linked into the C++ compiler only.
 102 #
 103 #  target_gtfiles       List of extra source files with type information.
 104 #
 105 #  xm_defines           List of macros to define when compiling for the

 115 #
 116 #  gdb_needs_out_file_path

 120 #  thread_file          Set to control which thread package to use.
 121 #
 122 #  gas                  Set to yes or no depending on whether the target
 123 #                       system normally uses GNU as.
 124 #
 125 #  need_64bit_hwint     Set to yes if HOST_WIDE_INT must be 64 bits wide
 126 #                       for this target.  This is true iff
 127 #                       MAX_LONG_TYPE_SIZE is 64.  (The code which
 128 #                       determines the underlying integral type for
 129 #                       HOST_WIDE_INT cannot see the definition of
