* Rewrite and cleanup unique_ptr tests.Eric Fiselier2017-04-15173-6899/+2380
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 The special members that have tests have very few test cases and are typically way out of date.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 Fiselier2017-04-132-7/+36
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: By manipulating a local variable in the loop, when the loop can be optimized away (due to no non-trivial destructors), this lets it be fully optimized away and we modify the __end_ separately. This results in a substantial improvement in the generated code. Prior to this change, this would be generated (on x86_64): movq (%rdi), %rdx movq 8(%rdi), %rcx cmpq %rdx, %rcx je LBB2_2 leaq -12(%rcx), %rax subq %rdx, %rax movabsq $-6148914691236517205, %rdx ## imm = 0xAAAAAAAAAAAAAAAB mulq %rdx shrq $3, %rdx notq %rdx leaq (%rdx,%rdx,2), %rax leaq (%rcx,%rax,4), %rax movq %rax, 8(%rdi) And after: movq (%rdi), %rax movq %rax, 8(%rdi) This brings this in line with what other implementations do.
