-# You will slowly go insane if you do not grok the following fact:  when
-# building v3 as part of the compiler, the top-level /target/ becomes the
-# library's /host/.  `configure' then causes --target to default to --host,
-# exactly like any other package using autoconf.  Therefore, 'target' and
-# 'host' will always be the same.  This makes sense both for native and
-# cross compilers, just think about it for a little while.  :-)
-#
-# Also, if v3 is being configured as part of a cross compiler, the top-level
-# configure script will pass the "real" host as $with_cross_host.
-#
-# AC 2.5x sets target_alias iff the user specified --target, but we use it
-# everywhere, so we set it here just to be sure.  In AC 2.13
-# AC_CANONICAL_TARGET was known as AC_CANONICAL_SYSTEM.

-# configure.target
-#
-# This shell script handles all target based configuration for libstdc++.
-# It sets various shell variables based on the the target and the
-# configuration options.  You can modify this shell script without needing
-# to rerun autoconf/aclocal/etc.  This file is "sourced" not executed.
-#
-# You should read docs/html/17_intro/porting.* to make sense of this file.
-#
-#
-# It uses the following shell variables as set by config.guess:
-#   target                The configuration target (full CPU-vendor-OS triplet)
-#   target_cpu            The configuration target CPU
-#   target_os             The configuration target OS
-#
-#
-# It sets the following shell variables:
-#
-#   cpu_include_dir        CPU-specific directory, defaults to cpu/generic
-#                          if cpu/target_cpu doesn't exist.  This is
-#                          used to set ATOMICITYH.
-#
-#   os_include_dir         OS-specific directory, defaults to os/generic.
-#
-#   c_model                the model to use for "C" headers, defaults to c_std.
-#
-#   c_compatibility        if "C" compatibility headers are necessary,
-#                          defaults to no.
-#
-#   abi_baseline_pair      directory name for ABI compat testing,
-#                          defaults to target (as per config.guess)
-#
-#   ATOMICITYH             location of atomicity.h,
-#                          defaults to cpu_include_dir
-#
-# It possibly modifies the following variables:
-#
-#   OPT_LDFLAGS            extra flags to pass when linking the library, of
-#                          the form '-Wl,blah'
-#                          (defaults to empty in acinclude.m4)
-#
-#
-# If the defaults will not work for your platform, you need only change the
-# variables that won't work, i.e., you do not need to explicitly set a
-# working variable to its default.  Most targets only need to change the two
-# *_include_dir variables.
-
-
-# DEFAULTS
-# Try to guess a default cpu_include_dir based on the name of the CPU.  We
-# cannot do this for os_include_dir; there are too many portable operating
-# systems out there.  :-)

-// Pthread-specific node allocator.
-// This is similar to the default allocator, except that free-list
-// information is kept separately for each thread, avoiding locking.
-// This should be reasonably fast even in the presence of threads.
-// The down side is that storage may not be well-utilized.
-// It is not an error to allocate memory in thread A and deallocate
-// it in thread B.  But this effectively transfers ownership of the memory,
-// so that it can only be reallocated by thread B.  Thus this can effectively
-// result in a storage leak if it's done on a regular basis.
-// It can also result in frequent sharing of
-// cache lines among processors, with potentially serious performance
-// consequences.

- *  allocators in the C++ standard, nor in the original H-P STL.  They do not
- *  encapsulate different pointer types; we assume that there is only one
- *  pointer type.  The C++ standard allocators are intended to allocate
- *  individual objects, not pools or arenas.
- *
- *  In this file allocators are of two different styles:  "standard" and
- *  "SGI" (quotes included).  "Standard" allocators conform to 20.4.  "SGI"
- *  allocators differ in AT LEAST the following ways (add to this list as you
- *  discover them):
- *
- *   - "Standard" allocate() takes two parameters (n_count,hint=0) but "SGI"
- *     allocate() takes one paramter (n_size).
- *   - Likewise, "standard" deallocate()'s argument is a count, but in "SGI"
- *     is a byte size.
- *   - max_size(), construct(), and destroy() are missing in "SGI" allocators.
- *   - reallocate(p,oldsz,newsz) is added in "SGI", and behaves as
- *     if p=realloc(p,newsz).
- *
- *  "SGI" allocators may be wrapped in __allocator to convert the interface
- *  into a "standard" one.
- *  @endif
- *
- *  @note The @c reallocate member functions have been deprecated for 3.2
- *        and will be removed in 3.4.  You must define @c _GLIBCPP_DEPRECATED
- *        to make this visible in 3.2; see c++config.h.
- *
- *  The canonical description of these classes is in docs/html/ext/howto.html
- *  or online at http://gcc.gnu.org/onlinedocs/libstdc++/ext/howto.html#3

-   *
-   *  Important implementation properties:
-   *  0. If globally mandated, then allocate objects from __new_alloc
-   *  1. If the clients request an object of size > _MAX_BYTES, the resulting
-   *     object will be obtained directly from __new_alloc

-   *     without permanently losing part of the object.
-   *
-   *  The first template parameter specifies whether more than one thread may
-   *  use this allocator.  It is safe to allocate an object from one instance
-   *  of a default_alloc and deallocate it with another one.  This effectively
-   *  transfers its ownership to the second one.  This may have undesirable

-   *  multiple default_alloc instances.  Note that containers built on different
-   *  allocator instances have different types, limiting the utility of this
-   *  approach.  If you do not wish to share the free lists with the main
-   *  default_alloc instance, instantiate this with a non-zero __inst.

-   *  Another allocator adaptor:  _Alloc_traits.  This serves two purposes.
-   *  First, make it possible to write containers that can use either "SGI"
-   *  style allocators or "standard" allocators.  Second, provide a mechanism
-   *  so that containers can query whether or not the allocator has distinct
-   *  instances.  If not, the container can avoid wasting a word of memory to
-   *  store an empty object.  For examples of use, see stl_vector.h, etc, or
-   *  any of the other classes derived from this one.
-   *
-   *  This adaptor uses partial specialization.  The general case of
-   *  _Alloc_traits<_Tp, _Alloc> assumes that _Alloc is a
-   *  standard-conforming allocator, possibly with non-equal instances and
-   *  non-static members.  (It still behaves correctly even if _Alloc has
-   *  static member and if all instances are equal.  Refinements affect
-   *  performance, not correctness.)
-   *
-   *  There are always two members:  allocator_type, which is a standard-
-   *  conforming allocator type for allocating objects of type _Tp, and
-   *  _S_instanceless, a static const member of type bool.  If
-   *  _S_instanceless is true, this means that there is no difference
-   *  between any two instances of type allocator_type.  Furthermore, if
-   *  _S_instanceless is true, then _Alloc_traits has one additional
-   *  member:  _Alloc_type.  This type encapsulates allocation and
-   *  deallocation of objects of type _Tp through a static interface; it
-   *  has two member functions, whose signatures are
-   *
-   *  -  static _Tp* allocate(size_t)
-   *  -  static void deallocate(_Tp*, size_t)
-   *
-   *  The size_t parameters are "standard" style (see top of stl_alloc.h) in
-   *  that they take counts, not sizes.

-	* genops.c (_IO_cleanup), libioP.h:  New function.  Call

-	destructors try to do output *after* _IO_cleanup is called.
-
-	Construct standard stdiobufs statically (using type punning).
-	* stdstrbufs.c;  Unless _STDIO_USES_IOSTREAM declare standard
-	stdiobufs (for stdin, stdout, and stderr), using type punning
-	(struct _IO_fake_stdiobuf).  This avoids constructor-time problems.
-	* stdstreams.cc:  Remove the declarations of the stdiobufs.

-Wed Jun 22 20:22:49 1994  Per Bothner  (bothner@kalessin.cygnus.com)
-

-	* gen-params:  Add code to determine _G_VTABLE_LABEL_HAS_LENGTH,

-	_G_USING_THUNKS, which describe how virtual function tables are named.
-	* stdfiles.c (FILEBUF_LITERAL):  Moved to libioP.h.

-	above changes.  Always, just return _strbuf.
-	* builtinbuf.h, builtinbuf.cc (builtinbuf::vtable,
-	builtinbuf::get_builtin_vtable):  Removed.  No longer needed.

-Thu Jun 16 17:33:50 1994  Per Bothner  (bothner@kalessin.cygnus.com)
-
-	* streambuf.h (ios::init):  Initialize all the fields.
-	This may be overkill, but the current ANSI working paper requires it.
-	* streambuf.h (ios::ios):  Reimplement in terms of ios::init.
-	* iostream.cc (Non-default constructors istream::istream,
-	ostream::ostream, iostream::iostream):  Cannot use a mem-initializer,

-	* libio.h (struct _IO_FILE_plus):  Move definition from here ...
-	* libioP.h (struct _IO_FILE_plus):  ... to here.  Since this
-	file is private to the implementation, we can rename the fields
-	from the implementor's to the user's name anme space.
-	(This avoids a lossage on SCO, whose stdio.h has a #define _file.)
-	* iofdopen.c, iofopen.c, stdfiles.c:  Fix field references accordingly.

-/* An fstream can be in at most one of put mode, get mode, or putback mode.
-   Putback mode is a variant of get mode.
-
-   In a filebuf, there is only one current position, instead of two
-   separate get and put pointers.  In get mode, the current position
-   is that of gptr(); in put mode that of pptr().
-
-   The position in the buffer that corresponds to the position
-   in external file system is normally _IO_read_end, except in putback
-   mode, when it is _IO_save_end.
-   If the field _fb._offset is >= 0, it gives the offset in
-   the file as a whole corresponding to eGptr(). (?)
-
-   PUT MODE:
-   If a filebuf is in put mode, then all of _IO_read_ptr, _IO_read_end,
-   and _IO_read_base are equal to each other.  These are usually equal
-   to _IO_buf_base, though not necessarily if we have switched from
-   get mode to put mode.  (The reason is to maintain the invariant
-   that _IO_read_end corresponds to the external file position.)
-   _IO_write_base is non-NULL and usually equal to _IO_base_base.
-   We also have _IO_write_end == _IO_buf_end, but only in fully buffered mode.
-   The un-flushed character are those between _IO_write_base and _IO_write_ptr.
-
-   GET MODE:
-   If a filebuf is in get or putback mode, eback() != egptr().
-   In get mode, the unread characters are between gptr() and egptr().
-   The OS file position corresponds to that of egptr().
-
-   PUTBACK MODE:
-   Putback mode is used to remember "excess" characters that have
-   been sputbackc'd in a separate putback buffer.
-   In putback mode, the get buffer points to the special putback buffer.
-   The unread characters are the characters between gptr() and egptr()
-   in the putback buffer, as well as the area between save_gptr()
-   and save_egptr(), which point into the original reserve buffer.
-   (The pointers save_gptr() and save_egptr() are the values
-   of gptr() and egptr() at the time putback mode was entered.)
-   The OS position corresponds to that of save_egptr().
-
-   LINE BUFFERED OUTPUT:
-   During line buffered output, _IO_write_base==base() && epptr()==base().
-   However, ptr() may be anywhere between base() and ebuf().
-   This forces a call to filebuf::overflow(int C) on every put.
-   If there is more space in the buffer, and C is not a '\n',
-   then C is inserted, and pptr() incremented.
-
-   UNBUFFERED STREAMS:
-   If a filebuf is unbuffered(), the _shortbuf[1] is used as the buffer.

-/* THE JUMPTABLE FUNCTIONS.
-
- * The _IO_FILE type is used to implement the FILE type in GNU libc,
- * as well as the streambuf class in GNU iostreams for C++.
- * These are all the same, just used differently.
- * An _IO_FILE (or FILE) object is allows followed by a pointer to
- * a jump table (of pointers to functions).  The pointer is accessed
- * with the _IO_JUMPS macro.  The jump table has a eccentric format,
- * so as to be compatible with the layout of a C++ virtual function table.
- * (as implemented by g++).  When a pointer to a streambuf object is
- * coerced to an (_IO_FILE*), then _IO_JUMPS on the result just
- * happens to point to the virtual function table of the streambuf.
- * Thus the _IO_JUMPS function table used for C stdio/libio does
- * double duty as the virtual function table for C++ streambuf.
- *
- * The entries in the _IO_JUMPS function table (and hence also the
- * virtual functions of a streambuf) are described below.
- * The first parameter of each function entry is the _IO_FILE/streambuf
- * object being acted on (i.e. the 'this' parameter).

-

-// Another allocator adaptor: _Alloc_traits.  This serves two
-// purposes.  First, make it possible to write containers that can use
-// either SGI-style allocators or standard-conforming allocator.
-// Second, provide a mechanism so that containers can query whether or
-// not the allocator has distinct instances.  If not, the container
-// can avoid wasting a word of memory to store an empty object.
-
-// This adaptor uses partial specialization.  The general case of
-// _Alloc_traits<_Tp, _Alloc> assumes that _Alloc is a
-// standard-conforming allocator, possibly with non-equal instances
-// and non-static members.  (It still behaves correctly even if _Alloc
-// has static member and if all instances are equal.  Refinements
-// affect performance, not correctness.)
-
-// There are always two members: allocator_type, which is a standard-
-// conforming allocator type for allocating objects of type _Tp, and
-// _S_instanceless, a static const member of type bool.  If
-// _S_instanceless is true, this means that there is no difference
-// between any two instances of type allocator_type.  Furthermore, if
-// _S_instanceless is true, then _Alloc_traits has one additional
-// member: _Alloc_type.  This type encapsulates allocation and
-// deallocation of objects of type _Tp through a static interface; it
-// has two member functions, whose signatures are
-//    static _Tp* allocate(size_t)
-//    static void deallocate(_Tp*, size_t)

-// * __STL_WIN32THREADS: defined if this is being compiled on a WIN32
-//   compiler in multithreaded mode.
-// * __STL_LONG_LONG if the compiler has long long and unsigned long long
-//   types.  (They're not in the C++ standard, but they are expected to be

-// User-settable macros that control compilation:

-// * __STL_NO_NAMESPACES: if defined, don't put the library in namespace
-//   std, even if the compiler supports namespaces.
-// * __STL_ASSERTIONS: if defined, then enable runtime checking through the
-//   __stl_assert macro.
-// * _PTHREADS: if defined, use Posix threads for multithreading support.
-// * _NOTHREADS: if defined, don't use any multithreading support.

-// * namespace-related macros (__STD, __STL_BEGIN_NAMESPACE, etc.)
-// * exception-related macros (__STL_TRY, __STL_UNWIND, etc.)
-// * __stl_assert, either as a test or as a null macro, depending on

- * requires a different performance tradeoff than the default.  If,
- * for example, your program contains many deques each of which contains
- * only a few elements, then you might want to save memory (possibly
- * by sacrificing some speed) by using smaller nodes.
- *
- * Unfortunately, some compilers have trouble with non-type template 
- * parameters; stl_config.h defines __STL_NON_TYPE_TMPL_PARAM_BUG if
- * that is the case.  If your compiler is one of them, then you will
- * not be able to use alternate node sizes; you will have to use the

-Red-black tree class, designed for use in implementing STL

-
-(1) the header cell is maintained with links not only to the root
-but also to the leftmost node of the tree, to enable constant time
-begin(), and to the rightmost node of the tree, to enable linear time
-performance when used with the generic set algorithms (set_union,
-etc.);
-
-(2) when a node being deleted has two children its successor node is
-relinked into its place, rather than copied, so that the only
-iterators invalidated are those referring to the deleted node.

-This header file provides a framework for allowing compile time dispatch
-based on type attributes. This is useful when writing template code.
-For example, when making a copy of an array of an unknown type, it helps
-to know if the type has a trivial copy constructor or not, to help decide
-if a memcpy can be used.
-
-The class template __type_traits provides a series of typedefs each of
-which is either __true_type or __false_type. The argument to
-__type_traits can be any type. The typedefs within this template will
-attain their correct values by one of these means:
-    1. The general instantiation contain conservative values which work
-       for all types.
-    2. Specializations may be declared to make distinctions between types.
-    3. Some compilers (such as the Silicon Graphics N32 and N64 compilers)
-       will automatically provide the appropriate specializations for all
-       types.
-
-EXAMPLE:
-
-//Copy an array of elements which have non-trivial copy constructors
-template <class T> void copy(T* source, T* destination, int n, __false_type);
-//Copy an array of elements which have trivial copy constructors. Use memcpy.
-template <class T> void copy(T* source, T* destination, int n, __true_type);
-
-//Copy an array of any type by using the most efficient copy mechanism
-template <class T> inline void copy(T* source,T* destination,int n) {
-   copy(source, destination, n,
-        typename __type_traits<T>::has_trivial_copy_constructor());

-
-	* lib/libstdc++.exp: Strip off leading LFs from both the pattern
- 	being matched against and the output from the board. Find the
- 	correct multilib libstdc++ to link with. Use g++_link_flags
- 	and libio_link_flags. Link in the status wrapper if needed.
