866569b8c3 Attempted locale refactoring. _LIBCPP_LOCALE__L_EXTENSIONS now should be defined if one has all of the xxx_l() functions. I've defined this for apple, freebsd and win32. _LIBCPP_HAS_DEFAULTRUNELOCALE should be defined if there is a _DefaultRuneLocale. I've defined this for apple and freebsd. The block of code we're trying to migrate away from is now under #ifdef __linux__. I've tested only on OS X. I hope I haven't broken things too badly elsewhere. Please let me know.

1c3ec6d480 Another installment on debug mode. This addresses list. However this should be considered a temporary state. The API of the debug database and how vector and list use it, is unsatisfactory at the moment. It is both inefficient and overly verbose. I wanted to get this functionality checked in though. In the next day or so I'll refactor what is there in an attempt to streamline things.

92a836c03d Reimplemented much of <istream> such that single character extractions do not check to see if this is the last character in the stream and thus never set eofbit. This fixes http://llvm.org/bugs/show_bug.cgi?id=10817 . This fix requires a recompiled libc++.dylib to be fully implemented. The recompiled libc++.dylib is ABI compatible with that shipped on Lion.

9d7530935d Revert r136547, r136545, and r136542 by removing slist. 
This was checked in without review. It is not clear its reasonable to
include with libc++ at all, and needs discussion at a highlevel before
moving forward.

It's also completely lacking tests, and included several bugs in the
implementation.

Original change:
Destruct elements of hash tables when removing individual entries from
the hash_table. I think this is the correct solution to PR10507, but I'm
not sure since this is a little bit cargo-culted. Howard, please review.

d50c1c7429 Include an "implementation" if SGI's slist. This was quickly hacked 
together to get it working with code, and is neither optimal
(erase(Iterator, Iterator) calculates the previous iterator twice,
rather than calculating the previous iterator of the first one, then
advancing it until the second is found) nor complete (splice() was not
implemented). Most of the implementation is borrowed from forward_list
via using-declarations.

110b8bf57e Explicitly invoke the size_type specialization of max and min. This 
avoids bugs where, when the allocator's size_type was smaller than int,
the multiplication or division would cause integral promotions and, with
two different integer types as arguments, deduction of the template
arguments would fail.

affd9e5d43 Add a new hash class in __gnu_ext for the extension containers. There 
are two motivations for this.

First, this allows users who are specializing __gnu_ext::hash to
continue doing so without changing their code.

Second, SGI specifies hash overloads for char* and const char* that
perform a hash of the string, not of the pointer.

In order to support this, the hashing code for string is factored out.

git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@136539 91177308-0d34-0410-b5e6-96231b3b80d8

e36a196049 Add two missing members from the extension hash containers. The first is 
the type name 'data_type', which is specified by the SGI spec as being
the correct type name for the mapped type. The second is an overload of
insert found in standard containers, taking an iterator as a 'hint'
(which we ignore in the standard containers as well). libstdc++'s
implementation includes these overloads, and they are needed to make
insert_iterator work (which I suspect is the real motivation for
including them in the standard containers).

The motivation for including these overloads of insert and leaving the
mapped_type typedef is to make it easier for clients to migrate to the
standard containers.

c97da3a590 Implement the __nolocale functions properly so that they will work on 
all platforms. Unfortunately a lot of this remains conditionally
compiled so as not to break Apple's ABI.

platforms that support _l suffixes for all functions in order to use
them.

62a6ac33a2 Implement generalized table lookups for upper, lower, and character 
traits.

To the best of my knowledge, this will not break the ABI for Apple.
However, it does introduce three publicly visible (although with
reserved name) functions that will fail to link against the just-shipped
Apple version of libc++. Since they are not used in any inline
functions, no actual breakage should occur.

If Howard doesn't want to put undefined functions (even internal ones)
into a header, they could be surrounded by additional conditional
compilation.

35d2fcfc8e Teach libc++ about the addressof() overloads it needs to work with 
Objective-C Automatic Reference Counting, where Objective-C object
pointers can have several different qualifiers (__strong, __weak,
__autoreleasing, __unsafe_unretained). These addressof() overloads are
only provided in ARC mode, and the __weak variant is conditionalized
on having weak-reference support in the ARC runtime.

For historical reasons, Clang provides these definitions itself, and
defines the macro _LIBCPP_PREDEFINED_OBJC_ARC_ADDRESSOF to note when
it as done so. The code belongs here, and this redundancy will be
eliminated in the future.

Addresses <rdar://problem/9658274>.

7604fea08c More fixes: One of my fixes to type_traits earlier today was incorrect, so that is reverted. Recently clang appears to have tightened up its definition of is_convertible and that has caused some failures in [unordered_][multi]map. I've switched to using is_constructible to restablish the desired functionality in [unordered_][multi]map. Specifically, inserting rvalues of move-only types for the keys.

bd89e4b0dd This is a simplified (and superior) implementation of __invoke, __invokable and __invoke_of. It is superior in that __invoke now handles reference qualified member functions whereas the previous implementation did not. And it simply has less infrastructure in its implementation. I'm still learning how to program in C++11 (and probably will be for a long time). This change does not impact the behavior we're seeing in http://llvm.org/bugs/show_bug.cgi?id=9975

57cff290a4 I had a giant misunderstanding of what 'synchronizes with' meant in [futures.async]/p5. This invalidated the current design of async in <future>. This is a new design, based on my new understanding, which has been confirmed on the lwg mailing list. The summary is that ~future() (and ~shared_future()) will block when they are created from within async, and the thread hasn't finished yet. As part of this work I created two new type traits: __invokable<F, Args...>::value and __invoke_of<F, Args...>::type. These are what result_of<F(Args...)> wanted to be when it grew up, but never will be. __invoke_of is carefully crafted so that it can serve as its own enable_if (type doesn't exist if the signature isn't invokable). All of this work is C++11 only.

b2080c70d4 Chris Jefferson spotted a problem with messages_base::catalog while getting libc++ to work on boost. The standard says this type must be an int. But this type is the key returned by the OS facility catopen. On OS X the type returned by catopen is void*, which doesn't fit into an int on 64 bit platforms. Chris suggested using ptrdiff_t instead of void*. It still isn't compliant with the standard, but chances are that this change will fix what is ailing boost. Chris also supplied the algorithm for distinguishing high-order pointers from error conditions. Thanks Chris.

497ac97247 Inline namespaces are always available in Clang. Rely on that without 
testing via __has_feature, since __has_feature for C++0x features no
longer evaluates true in C++98/03 mode.

Also, eliminate the redundant using directive. Inline namespaces make
their members visible in the enclosing namespace automatically.

5ea2e37c08 Remove an (incorrect) compiler workaround in the __mu function. The 
workaround relied on rvalue references binding to non-function
lvalues, while the original formulation (with std::forward) does the
right thing.

6c669943b3 An rvalue reference cannot bind to an lvalue, so static_cast the

f9e1c7e367 Eliminate the C++0x-only is_convertible testing function that accepts 
a cv-qualifier rvalue reference to the type, e.g.,

  template <class _Tp> char  __test(const volatile typename remove_reference<_Tp>::type&&);

The use of this function signature rather than the more
straightforward one used in C++98/03 mode, e.g.,

  template <class _Tp> char  __test(_Tp);

is broken in two ways:

  1) An rvalue reference cannot bind to lvalues, so is_convertible<X&,
  X&>::value would be false. This breaks two of the unique_ptr tests
  on Clang and GCC >= 4.5. Prior GCC's seem to have allowed rvalue
  references to bind to lvalues, allowing this bug to slip in.

  2) By adding cv-qualifiers to the type we're converting to, we get
  some incorrect "true" results for, e.g., is_convertible<const X&, X&>::value.

0e1493ec5e LWG 1385 [FCD] tuple_cat should be a single variadic signature (http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-active.html#1385). This issue is only in Ready status, meaning it is not official, but probably will be this March in Madrid. It was tentatively accepted in Batavia with the previso that Bill and I didn't have any problems implementing it. This is my part of that agreement.

770d1c4ea7 After a long break to wait for the atomic spec to settle, this completes the library part of <atomic>. It currently won't even parse as it depends on the existence of the intrinsics specified at http://libcxx.llvm.org/atomic_design_a.html. Everything has been tested using fake intrinsics which have now been removed. As the intrinsics come online, the ATOMIC_* macros will need to be adjusted to reflect which operations are lock-free. These macros will probably need to be #ifdef'd for each supported platform.
