Tim Northover 0090e657cb ARM64: compare RTTI names as strings 
ARM64 generates RTTI with hidden visibility, which means that typeinfo
must be compared char-by-char since it's not guaranteed to be uniqued
across the whole program.

Marshall Clow 1641a7c1cb Implement LWG issue #2135. If something goes wrong in condition_variable::wait, call terminate() rather than throwing an error. Do this indirectly, by marking the call as 'noexcept'. This is better than just calling terminate() directly, because it gives a better error message on the console.

shared_timed_mutex.

Peter Collingbourne 8845dbd798 Do not derive __gnu_cxx::hash<T> from std::hash<T>. 
Instead, define explicit specializations for the basic types listed in
the SGI documentation. This solves two problems:

 1) Helps avoid silent ODR violations caused by the absence of a
    user-supplied __gnu_cxx::hash specialization in cases where a std::hash
    specialization exists (e.g. for std::string).

 2) __gnu_cxx::hash semantics are slightly different to those of
    std::hash (for example, the former may dereference a pointer argument)
    so it is inappropriate for __gnu_cxx::hash to receive std::hash
    specializations by default.

Marshall Clow 78a87e8a68 Implement LWG 2193. Default constructors for standard library containers are explicit. Note that libc++ already did this for string/deque/forward_list/list/vector and the unordered containers; implement it for set/multiset/map/multimap. Add tests for all the containers. Two drive-by fixes as well: add a missing explicit in <deque>, and remove a tab that snuck into a container test. This issue is also LLVM bug 15724, and resolves it.

Error 1 error C2681: 'add_rvalue_reference<_Tp*>::type' : invalid expression
type for dynamic_cast c:\libcxx\include\type_traits

This is one more step getting libcxx compile under Visual C++. The patch is 
#if defined(_LIBCPP_MSVC) so will affect only this build.

When libcxx can be compiled, it will probably require the current version or
maybe even the next Update of Visual C++ 2013.

Howard Hinnant f9fd0d6d11 This is a followup to r194536, which changed the pair copy constructor to be 
trivial in C++03, thus making it trivial in both C++03 and C++11.

This patch allows one to opt-in/out of this decision with a macro.  You can
choose to have the pair copy constructor always be trivial, or always be
non-trivial.  The flag controlling this is now _LIBCPP_TRIVIAL_PAIR_COPY_CTOR.

The client can define this flag to 1, and the pair copy constructor will be
trivial (when possible of course), or to 0, and the pair copy constructor will
be nontrivial.

Default settings for this flag are set in <__config> (as usual).  With this
commit the default is _LIBCPP_TRIVIAL_PAIR_COPY_CTOR=1 for all platforms
except __APPLE__, which defaults to _LIBCPP_TRIVIAL_PAIR_COPY_CTOR=0.

Howard Hinnant ccad8c32e0 This fixes a very subtle ABI problem concerning the copy constructor of 
pair, and a couple of pair-like implementation detail types.  The
C++98/03 and 11 standards all specify that the copy constructor of
pair<int, int> is trivial. However as libc++ tracked the draft C++11
standard over the years, this copy constructor became non-trivial, and
then just recently was corrected back to trivial for C++11.

Unfortunately (for libc++1) the Itanium ABI specifies different calling
conventions for trivial and non-trivial copy constructors.  Therefore
currently the C++03 libc++ copy constructor for pair<int, int> is ABI
incompatible with the C++11 libc++ copy constructor for pair<int, int>.
This is Bad(tm).   This patch corrects the situation by making this copy
constructor trivial in C++03 mode as well.

Just in case it is needed for an incomplete C++11 compiler, libc++
retains the ability to support pair with rvalue references, but without
defaulted special members.  However the pair needs non-trivial special
members to implement this special case, (as it did when clang was in
this place a couple of years ago).

During this work a bug was also found and fixed in
is_trivially_constructible.

And there is a minor drive-by fix in <__config> regarding
__type_visibility__.

A test is updated to ensure that the copy constructor of pair<int, int>
is trivial in both C++03 and C++11.  This test will necessarily fail for
a compiler that implements rvalue references but not defaulted special
members.

Howard Hinnant a942f2ffd7 G M: The attached patch is for libcxx's new.cpp and __config files. The patch's intent is to make new.cpp compile using MS's cl.exe compiler without changing the meaning of anything for any other compiler. 
The issue this patch seeks to address is that MS's compiler (cl.exe) doesn't support the __attribute__((__weak__)) or __atribute__((__visibility__("default")) syntax; so a solution must be found where cl.exe doesn't see this syntax.

This patch seeks to solve this problem by changing code patterned like this:
__attribute__((__weak__, __visibility__("default")))
void* operator new(size_t size, const std::nothrow_t&) _NOEXCEPT { /*snip*/; return p; }

to code like this:
_LIBCPP_WEAK
void* operator new(size_t size, const std::nothrow_t&) _NOEXCEPT { return p; }

Howard:  Thanks for all the comments regarding the default visibility
tag on the definition.  I agree it isn't needed, and that there are lots
of other places where it is missing.  That being said, I'm not wanting
to rock the boat on that issue right now.  So I've added it back to the
definition via _LIBCPP_FUNC_VIS.  A later pass dedicated just to this
issue can bring things in to a consistent state one way or the other. 
Note that we do not want to have the exact same attributes on the
declaration and defintion in this case.  The declaration should not be
marked weak, whereas the definition should (which is what G M's patch
did). I've fully tested on OS X to ensure that the resultant attribute
syntax actually works.

Howard Hinnant 3af48ef76e G M: Changes all references to "x inline" to "inline x" where x = _libcpp_always_inline or _libcpp_inline_visibility macros. 
The patch touches these files:

locale
array
deque
new
string
utility
vector
__bit_reference
__split_buffer
locale_win32.h
 
There is no intended functionality change and it is expected that reversing the position of the inline keyword with regard to the other keywords does not change the meaning of anything, least not for apple/Linux etc.
 
It is intended to make libcxx more consistent with itself and to prevent the 1000 or so
"inline.cpp(3) : warning C4141: 'inline' : used more than once" warnings that MS's cl.exe compiler emits without this patch, i.e. if inline is not the first keyword before a function name etc.
 
Prefer "inline [other inline related keyword]" over "[other related keyword] inline".
After this patch, libcxx should be consistent to this pattern.

Additionally I decided to make this constructor trivial as well, as I could not come up with a rationale for not doing so. Fully tested with both current Apple clang and tip-of-trunk clang.

Howard Hinnant d7cda0680a Partial implementation of N3665. This paper was not voted into the C++1y draft. However I was looking at it and with some experimentation realized that I could partially implement it, and at the same time offer a performance optimization to cout. I simply added an xsputn override to the cout filebuf. The override does nothing special at all if there is a non-trivial codecvt installed. However if the codecvt returns true for always_noconv(), then this function can dump an entire string to fwrite, instead of doing it a character at a time under overflow(). This just makes sense. I stopped short of a full implementation of N3665 because in order to do so, xsputn would have to allocate a buffer when always_noconv() returned false, and I don't want to go to that expense.

Howard Hinnant 2f51de568f debug mode for unordered_map. Also picked up a missing check and test in unordered_multimap. This wraps up debug mode for the unordered containers. 
llvm-svn: 187659
 2013-08-02 17:50:49 +00:00
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.

llvm-svn: 187636
 2013-08-02 00:26:35 +00:00
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 4c80bfbd53 Debug mode for unordered_multimap. Some mods were done for unordered_map as well to keep all the tests passing. However unordered_map is at the very least still missing tests, if not functionality (if it isn't tested, it probably isn't working). 
llvm-svn: 187446
 2013-07-30 21:04:42 +00:00
Howard Hinnant e5c13decbe Debug mode for unordered_multiset. The exercise spotted a few places I had missed on unordered_set, so I picked those up as well. 
There are actually two debug modes:

   1.  -D_LIBCPP_DEBUG2 or -D_LIBCPP_DEBUG2=1
       This is a relatively expensive debug mode, but very thorough.  This is normally what you want to debug with, but may turn O(1) operations into O(N) operations.

   2.  -D_LIBCPP_DEBUG2=0
       This is "debug lite."  Only preconditions that can be checked with O(1) expense are checked.  For example range checking on an indexing operation.  But not iterator validity.

Howard Hinnant b24c802489 Debug mode for unordered_set. I believe this to be fairly complete for 
unordered_set, however it is not complete yet for unordered_multiset,
unordered_map or unordered_multimap.  There has been a lot of work done
for these other three containers, however that work was done just to
keep all of the tests passing.

You can try this out with -D_LIBCPP_DEBUG2.  You will have to link to a
libc++.dylib that has been compiled with src/debug.cpp.  So far, vector
(but not vector<bool>), list, and unordered_set are treated.  I hope to
get the other three unordered containers up fairly quickly now that
unordered_set is done.

The flag _LIBCPP_DEBUG2 will eventually be changed to _LIBCPP_DEBUG, but
not today.  This is my second effort at getting debug mode going for
libc++, and I'm not quite yet ready to throw all of the work under the
first attempt away.

The basic design is that all of the debug information is kept in a
central database, instead of in the containers.  This has been done as
an attempt to have debug mode and non-debug mode be ABI compatible with
each other.  There are some circumstances where if you construct a
container in an environment without debug mode and pass it into debug
mode, the checking will get confused and let you know with a readable
error message.  Passing containers the other way: from debug mode out to
a non-debugging mode container should be 100% safe (at least that is the
goal).

The tests use placement new to check that atomic values get properly zero-initialized. I had to modify the atomic_is_lock_free test, because default initialization of an object of const type 'const A' (aka 'const atomic<int>') requires a user-provided default constructor.

Howard Hinnant 575e4e3650 Richard Smith: It was pointed out to me off-list that libc++'s non-compiler-builtin 
implementation of std::is_polymorphic does this:

template <class _Tp> struct __is_polymorphic1 : public _Tp {};

... and that g++ rejects this if _Tp has an inaccessible virtual destructor
(because __is_polymorphic1<_Tp> would have a deleted virtual destructor
overriding _Tp's non-deleted destructor). Clang was failing to reject this;
I've fixed that in r178563, but that causes libc++'s corresponding test
case to fail with both clang and gcc when using the fallback
implementation. The fallback code also incorrectly rejects final types.

The attached patch fixes the fallback implementation of is_polymorphic; we
now use dynamic_cast's detection of polymorphic class types rather than
trying to determine if adding a virtual function makes the type larger:

  enable_if<sizeof((_Tp*)dynamic_cast<const volatile
void*>(declval<_Tp*>())) != 0, ...>

Two things of note here:
* the (_Tp*) cast is necessary to work around bugs in Clang and g++ where
we otherwise don't instantiate the dynamic_cast (filed as PR15656)
* the 'const volatile' is here to treat is_polymorphic<cv T> as true for a
polymorphic class type T -- my reading of the standard suggests this is
incorrect, but it matches our builtin __is_polymorphic and gcc

Howard Hinnant 92bd7c0337 Debug mode: learning to crawl. I need to set up some tests that actually test that the debug mode is working, but that won't cause problems when debug mode isn't on. This is my first prototype of such a test. It should call std::terminate() because it's comparing iterators from different containers. And std::terminate() is rigged up to exit normally. If debug mode fails, and doesn't call terminate, then the program asserts. The test is a no-op if _LIBCPP_DEBUG2 is not defined or is defined to be 0.

Howard Hinnant bfd96e11ed Hyeon-Bin Jeong: 1. sync() should reset it’s external buffer pointers. 
Remaining characters should be discarded once sync() called. If don’t, garbage
characters can be inserted to the front of external buffer in underflow().
Because underflow() copies remaining characters in external buffer to it’s
front. This results wrong characters insertion when seekpos() or seekoff() is
called.

this line should be inserted in sync() just before return:
__extbufnext_ = __extbufend_ = __extbuf_;

2. sync() should use length() rather than out() to calculate offset.
Reversing iterators and calling out() to calculate offset from behind is
working fine in stateless character encoding. However, in stateful encoding,
escape sequences could differ in length. As a result, out() could return wrong
length. 

For example, if we have internal buffer converted from this external sequence:
(capital letters mean escape sequence)
… a a a a B b b b b

out() produces this sequence. 
b b b b A a a a a

Because out() inserts escape sequence A rather than B, result sequence doesn't
match to external sequence. A and B could have different lengths, result offset
could be wrong value too.

length() method in codecvt is right for calculating offset, but it counts
offset from the beginning of buffer. So it requires another state member
variable to hold state before conversion.

Howard Hinnant aca09de378 Performance tweaking rotate. 
rotate is a critical algorithm because it is often used by other algorithms,
both std and non-std.  The main thrust of this optimization is a specialized
algorithm when the 'distance' to be shifted is 1 (either left or right).  To my
surprise, this 'optimization' was not effective for types like std::string.
std::string favors rotate algorithms which only use swap.  But for types like
scalars, and especially when the sequence is random access, these new
specializations are a big win.  If it is a vector<size_t> for example, the
rotate is done via a memmove and can be several times faster than the gcd
algorithm.

I'm using is_trivially_move_assignable to distinguish between types like int and
types like string.  This is obviously an ad-hoc approximation, but I haven't
found a case where it doesn't give good results.

I've used a 'static if' (with is_trivially_move_assignable) in three places. 
Testing with both -Os and -O3 showed that clang eliminated all code not be
executed by the 'static if' (including the 'static if' itself).

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 4cb38a82a2 This commit establishes a new bucket_count policy in the unordered containers: The policy now allows a power-of-2 number of buckets to be requested (and that request honored) by the client. And if the number of buckets is set to a power of 2, then the constraint of the hash to the number of buckets uses & instead of %. If the client does not specify a number of buckets, then the policy remains unchanged: a prime number of buckets is selected. The growth policy is that the number of buckets is roughly doubled when needed. While growing, either the prime, or the power-of-2 strategy will be preserved. There is a small run time cost for putting in this switch. For very cheap hash functions, e.g. identity for int, the cost can be as high as 18%. However with more typical use cases, e.g. strings, the cost is in the noise level. I've measured cases with very cheap hash functions (int) that using a power-of-2 number of buckets can make look up about twice as fast. However I've also noted that a power-of-2 number of buckets is more susceptible to accidental catastrophic collisions. Though I've also noted that accidental catastrophic collisions are also possible when using a prime number of buckets (but seems far less likely). In short, this patch adds an extra tuning knob for those clients trying to get the last bit of performance squeezed out of their hash containers. Casual users of the hash containers will not notice the introduction of this tuning knob. Those clients who swear by power-of-2 hash containers can now opt-in to that strategy. Clients who prefer a prime number of buckets can continue as they have.

Howard Hinnant 8b805c915a The rules for emplace in map, multimap, unordered_map and unordered_multimap changed a while back and I'm just now updating to these new rules. In a nutshell, you've got to know you're emplacing to a pair and use one of pair's constructors. I made one extension: If you want to emplace the key and default construct the mapped_type, you can just emplace(key), as opposed to emplace(piecewise_construct, forward_as_tuple(key), forward_as_tuple()).

Howard Hinnant 0527c6207a I believe tuple is still under development in the standard. Daniel Krugler is/will be making convincing arguments that a modified form of LWG 2051 (currently NAD Future) is easily acheivable and desirable. He has demonstrated that a tuple<T...> where all of the T are implicitly convertible from U... should have a tuple constructor that is also implicit, instead of explicit. This would support the use cases in LWG 2051 while not undermining T... with explicit conversions from U.... This check-in is an experimental implementation of Daniel's work. I believe this work to be mature enough to warrant inclusion into libc++. If anyone sees real-world problems that this check in causes, please let me know and I will revert it, and provide the feedback to the LWG.

Howard Hinnant 9b0cd149aa Version #next on the hash functions for scalars. This builds on Dave's work, extends it to T*, and changes the way double and long double are handled (no longer convert to float on 32 bit). I also picked up a minor bug with uninitialized bits on the upper end of size_t when sizeof(size_t) > sizeof(T), e.g. in hash<float>. Most of the functionality has been put in one place: __scalar_hash in <memory>. Unfortunately I could not reuse __scalar_hash for hash<long double> on x86 because of the padding bits which need to be zeroed. I didn't want to add this zeroing step to the more general __scalar_hash when it isn't needed (in the absence of padding bits). I'm not ignoring the hash<string> issue (possibly changing that to a better hash). I just haven't gotten there yet.

Howard Hinnant 9978e3709f 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.

Howard Hinnant 920b56ca88 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.

Alexis Hunt 1e846797dd 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.

Alexis Hunt 8324378195 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.

Alexis Hunt 8d2ed56644 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.

llvm-svn: 136539
 2011-07-29 23:31:56 +00:00
Alexis Hunt fe473ae277 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.

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.

Douglas Gregor 64ec101eb6 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>.

Howard Hinnant a945a32981 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.

Howard Hinnant b58f59cdb3 Second try at getting noexcept on move and swap for deque. I changed std::alloctor to propagate_on_container_move_assignment so as to make deque<T> move assignment noexcept. What we really need is a compile-time switch that says an allocator always compares equal.

Howard Hinnant 9eebe11dd5 I've become quite disatsified with the lack of noexcept specifications on container move construction, move assignment operator and swap. Without proper decoration on at least move construction, vectors of containers will have unacceptable performance. Here's the fix for deque.

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|.

Howard Hinnant 6282a4a1d3 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

Howard Hinnant ec0810e1c8 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.

Howard Hinnant 0c68ed006d 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.

Douglas Gregor a7b2241407 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.

Howard Hinnant 7f64810bc8 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.

Howard Hinnant d4a83d078c The implementation of the new definition of result_of (N3123) resulted in some test failures in [func.memfn] that I failed to previously notice. This corrects that mistake.

Howard Hinnant b5452b3db5 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.

Howard Hinnant 9847abacb1 Getting <atomic> warmed back up. We have a hopefully more stable spec now. And I believe the intrinsic spec at http://libcxx.llvm.org/atomic_design_a.html is still good.

Howard Hinnant 9b35c8275c Dave Zarzycki showed how the efficiency of shared_ptr could be significantly 
increased.  The following program is running 49% faster:

#include <iostream>
#include <memory>
#include <chrono>
#include <vector>
#include "chrono_io"

int main()
{
    typedef std::chrono::high_resolution_clock Clock;
    Clock::time_point t0 = Clock::now();
    {
        std::shared_ptr<int> p(new int (1));
        std::vector<std::shared_ptr<int> > v(1000000, p);
        v.insert(v.begin(), p);
        v.insert(v.begin(), p);
        v.insert(v.begin(), p);
        v.insert(v.begin(), p);
    }
    Clock::time_point t1 = Clock::now();
    std::cout << (t1-t0) << '\n';
}
