llvm-svn: 205507
 2014-04-03 03:13:12 +00:00
Marshall Clow 079402d1c1 Reword C++14 status to match C++11 status 
llvm-svn: 205505
 2014-04-03 02:38:12 +00:00
Marshall Clow ca6e366d07 Mark C++14 status as 'complete' 
llvm-svn: 205504
 2014-04-03 02:35:29 +00:00
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. 
llvm-svn: 204778
 2014-03-26 02:45:04 +00:00
Marshall Clow b43399842f Mark LWG issues #2075 and #2142 as complete. 2142 was a change to the standard 
to remove redundant wording, which required no changes to libc++. 2075 was a 
rewrite of the requirements for forward progress, and again, requires no changes
to the library.

llvm-svn: 204724
 2014-03-25 14:57:05 +00:00
Marshall Clow 4fdb070817 Add a test to make sure we're doing the right thing for throwing exceptions from deferred functions. This is LWG issue #2186. No change to the library needed. 
llvm-svn: 204678
 2014-03-24 22:25:24 +00:00
Marshall Clow e2db85a968 Mark LWG Issue #2288 as complete. This was wording cleanup, no code changes required. 
Also mark #2104 as complete. Leave the implementation in libc++ as noexcept, since 
implementations are allowed to add noexcept to non-virtual calls. If we throw from
unique_lock& operator=(unique_lock&& u), then that means the preconditions were violated,
and calling terminate() (as a result of throwing from a noexcept function) is as
good example of undefined behavior as any other.

David Majnemer 7ec93f9b1c Implement N3891: A proposal to rename shared_mutex to shared_timed_mutex 
This is as straightforward as it sounds, a renamed from shared_mutex to
shared_timed_mutex.

Note that libcxx .dylib and .so files built with c++14 support need to
be rebuilt.

 2014-03-17 20:19:44 +00:00
Marshall Clow 98de59157c Remove Issue #2235 from the Chicago section. The resolution was approved in Bristol (and it is listed there), and then is was approved *again* in Chicago. Thanks to STL @ microsoft for the catch 
llvm-svn: 203995
 2014-03-15 01:55:31 +00:00
Marshall Clow ef3d680093 Implement LWG 2360: 'reverse_iterator::operator*() is unimplementable'. Note that this is a (small) behavior change in the library. Reverse iterators whose base iterators' operator* return references to 'within themselves' have been sacrificed to the greater goal of avoiding data races. 
llvm-svn: 203587
 2014-03-11 17:16:17 +00:00
Marshall Clow ed94639ea1 Mark LWG #2314. 'apply() should return decltype(auto) and use decay_t before tuple_size' as complete. This is a correction to some example code in the standard, no change needed for libc++. 
llvm-svn: 203579
 2014-03-11 15:17:34 +00:00
Marshall Clow b33d838bcf Final bit for LWG #2263; test different allocator pointer types. Note that libc++ already does the right thing here; I've just added tests to ensure that it stays this way. 
llvm-svn: 203539
 2014-03-11 04:32:12 +00:00
Marshall Clow 17af2f56ab Add tests for LWG issue #2356. Stability of erasure in unordered associative containers. Libc++ already does this, but now we have tests for it. 
llvm-svn: 203494

llvm-svn: 202934
 2014-03-05 03:39:25 +00:00

llvm-svn: 202877
 2014-03-04 19:18:36 +00:00
Marshall Clow f519be343b Implement LWG 2324: Insert iterator constructors should use addressof(). Add two new container classes to the test suite that overload operator &, and add test cases to the insert/front_insert/back_insert iterator tests that use these containers. 
llvm-svn: 202741
 2014-03-03 19:20:40 +00:00
Marshall Clow 05c8dad230 Implement LWG Paper n3887: Consistent Metafunction Aliases. This adds std::tuple_element_t<> as an alias for tuple_element<>::type. Clean up the synopsis for tuple_element in <utility> as well. 
llvm-svn: 202673
 2014-03-03 06:18:11 +00:00
Marshall Clow 6a640a18a4 Implement LWG Issue #2285 - make_reverse_iterator. Also mark issues #1450 and #2205 as complete; they are just wording changes in the standard. Mark issues #2359, #2320 and #2322 as complete - libc++ implements them already. 
llvm-svn: 202671
 2014-03-03 01:24:04 +00:00
Marshall Clow 4ab4534964 More LWG issues. Mark #2182, #2323 and #2213 as complete. Add a test for #2339, and mark that as complete. No actual changes to the libc++ code; all of these were already in place. 
llvm-svn: 202407
 2014-02-27 16:13:36 +00:00
Marshall Clow c204c130fa LWG issue #2188: Reverse iterator does not fully support targets that overload operator&. Also mark #2272 and #2299 as complete; libc++ already implements them. 
llvm-svn: 202339
 2014-02-27 02:11:50 +00:00
Marshall Clow 16da324051 Implement LWG issue 2306: match_results::reference should be value_type&, not const value_type&. This is a general move by the LWG to have the reference type of read-only containers be a non-const reference; however, there are no methods that return a non-const reference to a match_result entry, so there's no worries about getting a non-const reference to a constant object. 
llvm-svn: 202214
 2014-02-26 01:56:31 +00:00
Marshall Clow 11918cff19 Mark LWG issue 2299 as complete. No code changes; libc++ already implements this.

llvm-svn: 192085
 2013-10-07 03:26:42 +00:00
Peter Collingbourne 26dd09e57f Make it possible to link against libstdc++ as well as libsupc++ with CMake. 
Linking against libstdc++, rather than libsupc++, is probably better
for people who need to link against clients of libstdc++.  Because
libsupc++ is provided only as a static library, its globals are not
shared between the static library and the copy linked into libstdc++.
This has been found to cause at least one test failure.

This also removes a number of symbols which were multiply defined
between libstdc++ and libc++, only when linking with libstdc++.

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.

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 9a20da75ef I believe this finishes up debug mode for list. The testing is a little weak, but I believe all of the functionality is there. Certainly enough for people to checkout and start beating up on.

Howard Hinnant 97b8ebe600 I believe debug mode for vector<T> (T != bool) is complete. If anyone sees anything more they would like to see on it, please let me know. Debug mode is activated by compiling with -D_LIBCPP_DEBUG2=1. Eventually _LIBCPP_DEBUG2 will be renamed to just _LIBCPP_DEBUG.
