C++14 support[1], adds more C++1z features[2], and fixes the following LWG issues[3]: 1450: Contradiction in regex_constants 2003: String exception inconsistency in erase. 2075: Progress guarantees, lock-free property, and scheduling assumptions 2104: unique_lock move-assignment should not be noexcept 2112: User-defined classes that cannot be derived from 2132: std::function ambiguity 2135: Unclear requirement for exceptions thrown in condition_variable::wait() 2142: packaged_task::operator() synchronization too broad? 2182: Container::[const_]reference types are misleadingly specified 2186: Incomplete action on async/launch::deferred 2188: Reverse iterator does not fully support targets that overload operator& 2193: Default constructors for standard library containers are explicit 2205: Problematic postconditions of regex_match and regex_search 2213: Return value of std::regex_replace 2240: Probable misuse of term "function scope" in [thread.condition] 2252: Strong guarantee on vector::push_back() still broken with C++11? 2257: Simplify container requirements with the new algorithms 2258: a.erase(q1, q2) unable to directly return q2 2263: Comparing iterators and allocator pointers with different const-character 2268: Setting a default argument in the declaration of a member function assign of std::basic_string 2271: regex_traits::lookup_classname specification unclear 2272: quoted should use char_traits::eq for character comparison 2278: User-defined literals for Standard Library types 2280: begin / end for arrays should be constexpr and noexcept 2285: make_reverse_iterator 2288: Inconsistent requirements for shared mutexes 2291: std::hash is vulnerable to collision DoS attack 2293: Wrong facet used by num_put::do_put 2299: Effects of inaccessible key_compare::is_transparent type are not clear 2301: Why is std::tie not constexpr? 2304: Complexity of count in unordered associative containers 2306: match_results::reference should be value_type&, not const value_type& 2308: Clarify container destructor requirements w.r.t. std::array 2313: tuple_size should always derive from integral_constant<size_t, N> 2314: apply() should return decltype(auto) and use decay_t before tuple_size 2315: weak_ptr should be movable 2316: weak_ptr::lock() should be atomic 2317: The type property queries should be UnaryTypeTraits returning size_t 2320: select_on_container_copy_construction() takes allocators, not containers 2322: Associative(initializer_list, stuff) constructors are underspecified 2323: vector::resize(n, t)'s specification should be simplified 2324: Insert iterator constructors should use addressof() 2329: regex_match()/regex_search() with match_results should forbid temporary strings 2330: regex("meow", regex::icase) is technically forbidden but should be permitted 2332: regex_iterator/regex_token_iterator should forbid temporary regexes 2339: Wording issue in nth_element 2341: Inconsistency between basic_ostream::seekp(pos) and basic_ostream::seekp(off, dir) 2344: quoted()'s interaction with padding is unclear 2346: integral_constant's member functions should be marked noexcept 2350: min, max, and minmax should be constexpr 2356: Stability of erasure in unordered associative containers 2357: Remaining "Assignable" requirement 2359: How does regex_constants::nosubs affect basic_regex::mark_count()? 2360: reverse_iterator::operator*() is unimplementable [1] http://libcxx.llvm.org/cxx1y_status.html [2] http://libcxx.llvm.org/cxx1z_status.html [3] http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-defects.html Exp-run: antoine MFC after: 1 month
