Howard Hinnant 42a3046eef Ok, 3 major changes for debug mode in one commit:
1.  I had been detecting and trapping iterator == and \!= among iterators
    in different containers as an error.  But the trapping itself is actually
    an error.
    
    Consider:
    
    #include <iostream>
    #include <vector>
    #include <algorithm>

    template <class C>
    void
    display(const C& c)
    {
        std::cout << "{";
        bool first = true;
        for (const auto& x : c)
        {
            if (\!first)
                std::cout << ", ";
            first = false;
            std::cout << x;
        }
        std::cout << "}\n";
    }

    int
    main()
    {
        typedef std::vector<int> V;
        V v1 = {1, 3, 5};
        V v2 = {2, 4, 6};
        display(v1);
        display(v2);
        V::iterator i = std::find(v1.begin(), v1.end(), 1);
        V::iterator j = std::find(v2.begin(), v2.end(), 2);
        if (*i == *j)
            i = j;    // perfectly legal
        // ...
        if (i \!= j)   // the only way to check
            v2.push_back(*i);
        display(v1);
        display(v2);
    }

    It is legal to assign an iterator from one container to another of the
    same type.  This is required to work.  One might want to test whether or
    not such an assignment had been made.  The way one performs such a check
    is using the iterator's ==, \!= operator.  This is a logical and necessary
    function and does not constitute an error.

2.  I had a header circular dependence bug when _LIBCPP_DEBUG2 is defined.
    This caused a problem in several of the libc++ tests.
    Fixed.

3.  There is a serious problem when _LIBCPP_DEBUG2=1 at the moment in that
    std::basic_string is inoperable.  std::basic_string uses __wrap_iterator
    to implement its iterators.  __wrap_iterator has been rigged up in debug
    mode to support vector.  But string hasn't been rigged up yet.  This means
    that one gets false positives when using std::string in debug mode.  I've
    upped std::string's priority in www/debug_mode.html.

Howard Hinnant 0be8f64c44 Nico Rieck: Currently _MSC_VER and _WIN32 are used to guard code which is
MSVC-specific, MSVCRT-specific, or Windows-specific. Because Clang can
also define _MSC_VER, and MSVCRT is not necessarily the only C runtime,
these macros should not be used interchangeably.

This patch divides all Windows-related bits into the aforementioned
categories. Two new macros are introduced:

- _LIBCPP_MSVC: Defined when compiling with MSVC. Detected using
  _MSC_VER, excluding Clang.
- _LIBCPP_MSVCRT: Defined when using the Microsoft CRT. This is the default
   when _WIN32 is defined.

This leaves _WIN32 for code using the Windows API.

This also corrects the spelling of _LIBCP_HAS_IS_BASE_OF to _LIBCPP_HAS_IS_BASE_OF.

Nico, please prepare a patch for CREDITS.TXT, thanks.

Howard Hinnant 8bd1771abe Matthew Dempsky: POSIX defines that the _POSIX_C_SOURCE macros are to be set by user
code to specify what version of POSIX the system should provide.  If
you want to check what version of POSIX is actually available, you're
supposed to test _POSIX_VERSION.

However, since sysconf() has been in POSIX since 1995, it's probably
safe to assume it's available on any system with a C++11 compiler,
especially if _SC_NPROCESSORS_ONLN is defined too.  So no point in a
complicated preprocessor rule if just we unconditionally include
<unistd.h> (on non-Windows systems).

Also, I've added a #warning for to help porters detect when a suitable
implementation isn't detected at compile-time.

Howard:  Matthew, can you patch CREDITS.TXT?  Thanks.

Howard Hinnant 2446649c1e Saleem Abdulrasool: If errno is defined as volatile int, the qualifier differences can cause

Howard Hinnant aad745a024 Change sleep_for, sleep_until, and the condition_variable timed wait
functions to protect against duration and time_point overflow.  Since
we're about to wait anyway, we can afford to spend a few more cycles on
this checking.  I purposefully did not treat the timed try_locks with
overflow checking.  This fixes
http://llvm.org/bugs/show_bug.cgi?id=13721 .  I'm unsure if the standard
needs clarification in this area, or if this is simply QOI.  The
<chrono> facilities were never intended to overflow check, but just to
not overflow if durations stayed within +/- 292 years.

Howard Hinnant 4df0a6adf6 Andrew Morrow: Among the various libc++ tests that currently don't pass on Linux are
localization/locale.categories/category.collate/category.ctype/locale.ctype.byname/is_1.pass.cpp
and scan_is.pass.cpp. The tests fail when the character class being
tested is compound, like ctype_base::alnum or ctype_base::graph,
because the existing series of conditionals in do_is an do_scan_is
will abort too early. For instance, if the character class being
tested is alnum, and the character is numeric, do_is will return false
because iswalpha_l will return false, 'result' becomes false, and the
'true' result from the later call to iswdigit_l ends up being ignored
. A similar problem exists in do_scan_is.

Howard Hinnant 088e37c77a Despite my pathological distrust of spin locks, the number just don't lie. I've put a small spin in __sp_mut::lock() on std::mutex::try_lock(), which is testing quite well. In my experience, putting in a yield for every failed iteration is also a major performance booster. This change makes one of the performance tests I was using (a highly contended one) run about 20 times faster.

Howard Hinnant d77851e837 Implement [util.smartptr.shared.atomic]. This is the last unimplemented
section in libc++.  This requires a recompiled dylib.  Failure to rebuild
the dylib will result in a link-time error if and only if the functions from
[util.smartptr.shared.atomic] are used.

The implementation is not lock free.  After considerable thought, I know of no
way to make the implementation lock free.  Ideas welcome along that front.  But
changing the ABI of shared_ptr is not on the table at this point.

The mutex used to lock these function is encapsulated by std::__sp_mut.  The
only thing the client knows about std::__sp_mut is that it has a void* data
member, can't be constructed, and has lock and unlock members.  Within the
binary __sp_mut is currently implemented as a pointer to a std::mutex.  That can
change in the future without disturbing the ABI (as long as sizeof(__sp_mut)
remains constant.

I specifically did not make __sp_mut a spin lock as I have a pathological
distrust of spin locks.  Testing on OS X reveals that the use of std::mutex in
this role is not a large performance penalty as long as the contention for the
mutex is low (more likely to get the lock than to have to wait).  In the future
we can still make __sp_mut a spin lock if that is what is desired (without ABI
damage).

The dylib contains 16 __sp_mut's to be chosen based on the hash of the address
of the shared_ptr.  The constant 16 is a ball-park reasonable space/time
tradeoff.

std::hash<T*> was changed to call __murmur2_or_cityhash, instead of the identity
function.  I had thought we had already done this, but I was mistaken.

All of this is under #if __has_feature(cxx_atomic) even though the
implementation is not lock free, because the signatures require access to
std::memory_order, which is currently available only under
__has_feature(cxx_atomic).

Howard Hinnant dce0696a36 Patch by Andrew C. Morrow: Conditionally include cxxabi.h in new.cpp and typeinfo.cpp. Both new.cpp and typeinfo.cpp have code that is conditionally compiled
based on the LIBCXXRT and _LIBCPPABI_VERSION defines, but those files
do not currently include <cxxabi.h> in the non __APPLE__ case. The
attached patch updates those files so that for non __APPLE__ builds
<cxxabi.h> is included if available or if LIBCXXRT is set. I'm
modeling this on the recent updates to exception.cpp.

Richard Smith 11ffde3d7e libc++: only #include <cxxabi.h> if it exists. This allows libc++ to build
out of the box on Linux systems. If you're building against libc++abi, you
still need to make sure it can find <cxxabi.h> so it knows not to export
symbols which libc++abi provides.

Alexis Hunt 8a02a632be 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.

them.

Alexis Hunt 3f60bca9e9 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.

My rationale was: If a std-dicated noexcept function needs to call another std-defined function, that called function must be noexcept. We're all a little new to noexcept, so things like this are to be expected. Also included fix for broken __is_swappable trait pointed out by Marc Glisse, thanks Marc|. And fixed a test case for is_nothrow_destructible. Destructors are now noexcept by default|

Weaker atomics in the library automatically try stronger and stronger variants, picking the weakest compiler intrinsic available. If no compiler intrinsics are available for a given operation, the library locks a mutex and does the job. Better documentation to follow...

Howard Hinnant 128ba7191d patch by Jeffrey Yasskin for porting to Ubuntu Hardy. Everything was accepted except there were some bug fixes needed in <locale> for the __nolocale_* series. For the apple branch I ended up using templates instead of the var_args solution because it seemed both safer and more efficient.
