* Make std::is_assignable tolerate references to incomplete types.Eric Fiselier2016-07-251-2/+5
| | | | llvm-svn: 276599
* Revert r276548 - Make pair/tuples assignment operators SFINAE properly.Eric Fiselier2016-07-255-310/+2
| | | | | | | | | | | | This is a breaking change. The SFINAE required is instantiated the second the class is instantiated, and this can cause hard SFINAE errors when applied to references to incomplete types. Ex. struct IncompleteType; extern IncompleteType it; std::tuple<IncompleteType&> t(it); // SFINAE will blow up. llvm-svn: 276598
* Don't SFINAE pair's copy assignment operator in C++03 mode.Eric Fiselier2016-07-251-0/+36
| | | | | | | | In C++03 mode evaluating the SFINAE can cause a hard error due to access control violations. This is a problem because the SFINAE is evaluated as soon as the class is instantiated, and not later. llvm-svn: 276594

* Fix inheriting constructor test for std::function.Eric Fiselier2016-07-201-4/+7
| | | | | | | The test I originally checked in only worked with ToT Clang. This patch updates the test so that it works as far back as 3.5. llvm-svn: 276093
* Unbreak is_constructible tests for Clang <= 3.7.Eric Fiselier2016-07-202-1/+25
| | | | | | | There is a bug in Clang's __is_constructible builtin that causes it to return true for function types; ex [T = void()]. llvm-svn: 276092
* Add missed test in r276090.Eric Fiselier2016-07-201-0/+23
| | | | llvm-svn: 276091
* Reimplement is_constructible fallback implementation. Fixes PR21574.Eric Fiselier2016-07-202-7/+60
| | | | | | | The previous implementation relied highly on specializations to handle special cases. This new implementation lets the compiler do the work when possible. llvm-svn: 276084

* Implement C++17 tuple bits. Including apply and make_from_tuple.Eric Fiselier2016-07-187-0/+1151
| | | | | | | | | | This patch upgrades <tuple> to be C++17 compliant by implementing: * tuple_size_v: This was forgotten when implementing the other _v traits. * std::apply: This was added via LFTS v1 in p0220r1. * std::make_from_tuple: This was added in p0209r2. llvm-svn: 275745

* Flatten the tuple_element and __make_tuple_types implementations.Eric Fiselier2016-07-011-0/+34
| | | | | | | | | | This patch attempts to improve the QoI of std::tuples tuple_element and __make_tuple_types helpers. Previously they required O(N) instantiations, one for every element in the tuple The new implementations are O(1) after __tuple_indices<Id...> is created. llvm-svn: 274330

* Implement P0163r0. Add shared_ptr::weak_type.Eric Fiselier2016-06-271-0/+6
| | | | | | | | | | This patch adds the weak_type typedef in shared_ptr. It is available in C++17 and newer. This patch also updates the _LIBCPP_STD_VER and TEST_STD_VER macros to have the value of 16, since 2016 is the current year. llvm-svn: 273839

* Fix PR27115 - enable_shared_from_this does not work as a virtual base class.Eric Fiselier2016-06-261-0/+16
| | | | | | | | | | | | | See https://llvm.org/bugs/show_bug.cgi?id=27115 The problem was that the conversion from 'const enable_shared_from_this<T>*' to 'const T*' didn't work if T inherited enable_shared_from_this as a virtual base class. The fix is to take the original pointer passed to shared_ptr's constructor in the __enable_weak_this method and perform an upcast to 'const T*' instead of performing a downcast from the enable_shared_from_this base. llvm-svn: 273835
* Implement LWG 2488 - Make the placeholders constexpr.Eric Fiselier2016-06-261-0/+28
| | | | | | | | | | | | | | | | | | | This patch makes the bind placeholders in std::placeholders both (1) const and (2) constexpr (See below). This is technically a breaking change for any code using the placeholders outside of std::bind and depending on them being non-const. However I don't think this will break any real world code. (1) Previously the placeholders were non-const extern globals in all dialects. This patch changes these extern globals to be const in all dialects. Since the cv-qualifiers don't participate in name mangling for globals this is an ABI compatible change. (2) Make the placeholders constexpr in C++11 and beyond. Although LWG 2488 only applies to C++17 I don't see any reason not to backport this change. llvm-svn: 273824

| | | | | | | | | | | | | | | | | some cases. Libc++ has to deduce the 'allocator_arg_t' parameter as 'AllocArgT' for the following constructor: template <class Alloc> tuple(allocator_arg_t, Alloc const&) Previously libc++ has tried to support tags derived from 'allocator_arg_t' by using 'is_base_of<AllocArgT, allocator_arg_t>'. However this breaks whenever a 2-tuple contains a reference to an incomplete type as its first parameter. See https://llvm.org/bugs/show_bug.cgi?id=27684 llvm-svn: 273334
