These tests were unconditionally asserting that optional and unique_ptr declare throwing hashes, but MSVC++ implements conditional noexcept forwarding that of the underlying hash function. As a result we were failing these tests but there's nothing forbidding strengthening noexcept in that way. Changed the ASSERT_NOT_NOEXCEPT asserts to use types which themselves have non-noexcept hash functions. llvm-svn: 300516

* Overhaul unique_ptr - Implement LWG 2801, 2905, 2520.Eric Fiselier2017-04-1615-67/+746
| | | | | | | | | | | | | | | | | | | | | This patch overhauls both specializations of unique_ptr while implementing the following LWG issues: * LWG 2801 - This issue constrains unique_ptr's constructors when the deleter type is not default constructible. Additionally it adds SFINAE conditions to unique_ptr<T[]>::unique_ptr(Up). * LWG 2905 - This issue reworks the unique_ptr(pointer, /* see below */ deleter) constructors so that they correctly SFINAE when the deleter argument cannot be used to construct the stored deleter. * LWG 2520 - This issue fixes initializing unique_ptr<T[]> from nullptr. Libc++ had previously implemented this issue, but the suggested resolution still broke initialization from NULL. This patch re-works the unique_ptr<T[]>(Up, deleter) overloads so that they accept NULL as well as nullptr. llvm-svn: 300406

* Rewrite and cleanup unique_ptr tests.Eric Fiselier2017-04-15171-6899/+2208
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch almost entirely rewrites the unique_ptr tests. There are a couple of reasons for this: A) Most of the *.fail.cpp tests were either incorrect or could be better written as a *.pass.cpp test that uses <type_traits> to check if certain operations are valid (Ex. Using static_assert(!std::is_copy_constructible_v<T>) instead of writing a failure test). B) [unique.ptr.runtime] has very poor test coverage. Many of the constructors and assignment operators have to tests at all. The special members that have tests have very few test cases and are typically way out of date. C) The tests for [unique.ptr.single] and [unique.ptr.runtime] are largely duplicates of each other. This means common requirements have two different sets of tests in two different test files. This makes the tests harder to maintain than if there was a single copy. To address (A) this patch changes almost all of the *.fail.cpp tests into .pass.cpp tests using type traits; Allowing the *.fail.cpp tests to be removed. The address (B) and (C) the tests for [unique.ptr.single] and [unique.ptr.runtime] have been combined into a single directory, allowing both specializations to share common tests. Tests specific to the single/runtime specializations are given the suffix "*.single.pass.cpp" or "*.runtime.pass.cpp". Finally the unique.ptr test have been moved into the correct directory according to the standard. Specifically they have been removed from "utilities/memory" into "utilities/smartptr". PS. This patch also adds newly written tests for upcoming unique_ptr changes/fixes. However since these tests don't currently pass they are guarded by the macro TEST_WORKAROUND_UPCOMING_UNIQUE_PTR_CHANGES. This allows other STL's to validate the tests before libc++ implements the changes. The relevant libc++ changes should land in the next week. llvm-svn: 300388

* Diagnose when reverse_iterator is used on path::iterator.Eric Fiselier2017-04-131-7/+5
| | | | | | | | | | | | | | | path::iterator isn't a strictly conforming iterator. Specifically it stashes the current element inside the iterator. This leads to UB when used with reverse_iterator since it requires the element to outlive the lifetime of the iterator. This patch adds a static_assert inside reverse_iterator to disallow "stashing iterator types", and it tags path::iterator as such a type. Additionally this patch removes all uses of reverse_iterator<path::iterator> within the tests. llvm-svn: 300164

* Add tests that std::unique_ptr's default constructor is constexpr.Eric Fiselier2017-04-133-49/+50
| | | | | | | | | | | | std::unique_ptr's default constructor must be constexpr in order to allow constant initialization to take place for static objects; Even though we can never have a constexpr unique_ptr variable since it's not a literal type. This patch adds tests that constant initialization takes place by using the __attribute__((require_constant_initialization)) macro. llvm-svn: 300158
* Fix most failures caused by r300140Eric Fiselier2017-04-131-1/+1
| | | | | | | | | | | | | | | | | | | | | r300140 introduced a bunch of failures by changing the internal interface provided by __compressed_pair. This patch fixes all of the failures caused by the new interface by changing the existing code to use it. In addition to those changes this patch also fixes two separate issues causing test failures: 1) Fix the member swap definition for __map_value_compare. Previously the swap was incorrectly configured to swap the comparator as const. 2) Fix an assertion failure in futures.task.members/ctor_func_alloc.pass.cpp that incorrectly expected a move to take place when a single copy is sufficient. There is one remaining failure regarding make_shared. I'll commit a fix for that shortly. llvm-svn: 300148
* [libcxx] Fix __compressed_pair so it doesn't copy the argument multiple ↵Eric Fiselier2017-04-121-13/+14
| | | | | | | | | | | | | | | | | | | | | times, and add constexpr. Summary: __compressed_pair takes and passes it's constructor arguments by value. This causes arguments to be moved 3 times instead of once. This patch addresses that issue and fixes `constexpr` on the constructors. I would rather have this fix than D27564, and I'm fairly confident it's not ABI breaking but I'm not 100% sure. I prefer this solution because it removes a lot of code and makes the implementation *much* smaller.

| | | | | | | | | | | For reference deleter types the const qualifier on the return type of get_deleter() should be ignored, and a non-const deleter should be returned. This patch fixes a bug where "const deleter_type&" is incorrectly formed. llvm-svn: 300121
