* Fix XPASS buildbot failure related to structured bindingsEric Fiselier2017-01-051-1/+1
| | | | | | | | | | | The test was previously set to XFAIL if __cpp_structured_bindings wasn't defined. However there are Clang 4.0 versions which do not define this macro but do provide structured bindings, which causes the test to pass unexpectedly. This patch changes the XFAIL to an UNSUPPORTED. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@291060 91177308-0d34-0410-b5e6-96231b3b80d8

* [libcxx] Re-implement LWG 2770 again: Fix tuple_size to work with structured ↵Eric Fiselier2017-01-045-18/+307
| | | | | | | | | | | | | | | | | | | bindings Summary: This patch attempts to re-implement a fix for LWG 2770, but not the actual specified PR. The PR for 2770 specifies tuple_size<T const> as only conditionally providing a `::value` member. However C++17 structured bindings require `tuple_size<T const>` to be complete only if `tuple_size<T>` is also complete. Therefore this patch implements only provides the specialization `tuple_size<T CV>` iff `tuple_size<T>` is a complete type. This fixes http://llvm.org/PR31513.

* [libcxx] Fix tuple construction/assignment from types derived from ↵Eric Fiselier2016-12-142-0/+263
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tuple/pair/array. Summary: The standard requires tuple have the following constructors: ``` tuple(tuple<OtherTypes...> const&); tuple(tuple<OtherTypes...> &&); tuple(pair<T1, T2> const&); tuple(pair<T1, T2> &&); tuple(array<T, N> const&); tuple(array<T, N> &&); ``` However libc++ implements these as a single constructor with the signature: ``` template <class TupleLike, enable_if_t<__is_tuple_like<TupleLike>::value>> tuple(TupleLike&&); ``` This causes the constructor to reject types derived from tuple-like types; Unlike if we had all of the concrete overloads, because they cause the derived->base conversion in the signature. This patch fixes this issue by detecting derived types and the tuple-like base they are derived from. It does this by creating an overloaded function with signatures for each of tuple/pair/array and checking if the possibly derived type can convert to any of them.

(Moving the definitions of ASSERT_NOEXCEPT/ASSERT_NOT_NOEXCEPT isn't technically necessary because they're macros, but I think it's better style to define stuff before using it.) test/std/utilities/tuple/tuple.tuple/tuple.apply/apply.pass.cpp There was a completely unused `TrackedCallable obj;`. apply() isn't depicted with conditional noexcept in C++17. test/std/utilities/tuple/tuple.tuple/tuple.apply/make_from_tuple.pass.cpp Now that we have LIBCPP_ASSERT_NOEXCEPT, use it.

* Fix PR27374 - Remove the implicit reduced-arity-extension in tuple.Eric Fiselier2016-12-081-7/+14
| | | | | | | | | | | | | | | | | | | This patch removes libc++'s tuple extension which allowed it to be constructed from fewer initializers than elements; with the remaining elements being default constructed. However the implicit version of this extension breaks conforming code. For example: int fun(std::string); int fun(std::tuple<std::string, int>); int x = fun("hello"); // ambigious Because existing code may already depend on this extension it can be re-enabled by defining _LIBCPP_ENABLE_TUPLE_IMPLICIT_REDUCED_ARITY_EXTENSION. Note that the explicit version of this extension is still supported, although it's somewhat less useful than the implicit one. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@289158 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | loss of data", part 5/7. Instead of storing double in double and then truncating to int, store int in long and then widen to long long. This preserves test coverage (as these tests are interested in various tuple conversions) while avoiding truncation warnings. test/std/utilities/tuple/tuple.tuple/tuple.cnstr/const_pair.pass.cpp Since we aren't physically truncating anymore, t1 is equal to p0. test/std/utilities/tuple/tuple.tuple/tuple.cnstr/convert_copy.pass.cpp One edit is different from the usual pattern. Previously, we were storing double in double and then converting to A, which has an implicitly converting constructor from int. Now, we're storing int in int and then converting to A, avoiding the truncation. Fixes D27542. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@289109 91177308-0d34-0410-b5e6-96231b3b80d8
