* Recommit r276548 - Make pair/tuples assignment operators SFINAE properly.Eric Fiselier2016-07-252-0/+118

* Revert r276548 - Make pair/tuples assignment operators SFINAE properly.Eric Fiselier2016-07-252-118/+0
| | | | | | | | | | | | 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

| | | | | | | | | | 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

| | | | | | | | | | | | | | | | | 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

* [libcxx] Improve tests to use the UNSUPPORTED lit directiveAsiri Rathnayake2016-05-284-16/+0
| | | | | | | | | | | | | | | | | | | Quite a few libcxx tests seem to follow the format: #if _LIBCPP_STD_VER > X // Do test. #else // Empty test. #endif We should instead use the UNSUPPORTED lit directive to exclude the test on earlier C++ standards. This gives us a more accurate number of test passes for those standards and avoids unnecessary conflicts with other lit directives on the same tests.

* Cleanup and guard tuple's constructor SFINAE. Fixes PR22806 and PR23256.Eric Fiselier2016-04-153-2/+278
| | | | | | | | | | | | | | | | | | | | | There are two main fixes in this patch. First the constructor SFINAE was changed so that it's evaluated in two stages where the first stage evaluates the "safe" SFINAE conditions and the second evaluates the "dangerous" ones. The key is that the second stage is lazily evaluated only if the first stage passes. This helps fix PR23256 (https://llvm.org/bugs/show_bug.cgi?id=23256). The second fix is for PR22806 and LWG issue 2549. This fix applies the suggested resolution to the LWG issue in order to prevent the construction of dangling references. The SFINAE for this check is contained within the _PreferTupleLikeConstructor alias template. The tuple-like constructors are disabled whenever that trait returns false.

* [libcxx] Remove the "reduced-arity-initialization" extension from the ↵Eric Fiselier2016-04-152-55/+98
| | | | | | | | | | | | | | | | | uses-allocator constructors Summary: A default uses-allocator constructor has been added since that overload was previously provided by the extended constructor. Since Clang does implicit conversion checking after substitution this constructor has to deduce the allocator_arg_t parameter so that it can prevent the evaluation of "is_default_constructible" if the first argument doesn't match. See http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#1391 for more information.

* [libc++] Try and prevent evaluation of `is_default_constructible` on tuples ↵Eric Fiselier2015-02-211-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | default constructor if it is not needed. Summary: Currently parts of the SFINAE on tuples default constructor always gets evaluated even when the default constructor is never called or instantiated. This can cause a hard compile error when a tuple is created with types that do not have a default constructor. Below is a self contained example using a pair like class. This code will not compile but probably should. ``` #include <type_traits> template <class T> struct IllFormedDefaultImp { IllFormedDefaultImp(T x) : value(x) {} constexpr IllFormedDefaultImp() {} T value; }; typedef IllFormedDefaultImp<int &> IllFormedDefault; template <class T, class U> struct pair { template <bool Dummy = true, class = typename std::enable_if< std::is_default_constructible<T>::value && std::is_default_constructible<U>::value && Dummy>::type > constexpr pair() : first(), second() {} pair(T const & t, U const & u) : first(t), second(u) {} T first; U second; }; int main() { int x = 1; IllFormedDefault v(x); pair<IllFormedDefault, IllFormedDefault> p(v, v); } ``` One way to fix this is to use `Dummy` in a more involved way in the constructor SFINAE. The following patch fixes these sorts of hard compile errors for tuple.
