2019-01-16Move internal usages of `alignof`/`__alignof` to use `_LIBCPP_ALIGNOF`. Eric Fiselier
Summary: Starting in Clang 8.0 and GCC 8.0, `alignof` and `__alignof` return different values in same cases. Specifically `alignof` and `_Alignof` return the minimum alignment for a type, where as `__alignof` returns the preferred alignment. libc++ currently uses `__alignof` but means to use `alignof`. See llvm.org/PR39713 This patch introduces the macro `_LIBCPP_ALIGNOF` so we can control which spelling gets used. This patch does not introduce any ABI guard to provide the old behavior with newer compilers. However, if we decide that is needed, this patch makes it trivial to implement. I think we should commit this change immediately, and decide what we want to do about the ABI afterwards.

2019-01-16Implement feature test macros using a script.Eric Fiselier
Summary: This patch implements all the feature test macros libc++ currently supports, as specified by the standard or cppreference prior to C++2a. The tests and `<version>` header are generated using a script. The script contains a table of each feature test macro, the headers it should be accessible from, and its values of each dialect of C++. When a new feature test macro is added or needed, the table should be updated and the script re-run.

Summary: The tests need to create files larger than 2GB, but size_t is 32-bit on a 32-bit system. Make use of explicit off64_t APIs so we can still use a default off_t for the tests while enabling 64-bit file offsets for create_file.

2019-01-11[libcxx] Call __count_bool_true for bitset countAdhemerval Zanella
This patch aims to help clang with better information so it can inline __bit_reference count function usage for both std::biset. Current clang inliner can not infer that the passed typed will be used only to select the optimized variant, it evaluates the type argument and type check as a load plus compare (although later optimization phases correctly optimized this out). It is mainly to help llvm inliner to generate better code for std::bitset count for aarch64. It helps on both runtime and code size, since if inline decides that _VSTD::count should not be inlined the vectorization will create both aligned and unaligned variants (which add both code size and runtime costs) llvm-svn: 350936

2019-01-10[libcxx] Reorganize tests since the application of P0602R4Louis Dionne
Summary: P0602R4 makes the special member functions of optional and variant conditionally trivial based on the types in the optional/variant. We already implemented that, but the tests were organized as if this were a non-standard extension. This patch reorganizes the tests in a way that makes more sense since this is not an extension anymore.

range with const-ness mismatch. We already have a specialization that will use memcpy for construction of trivial types from an iterator range like std::vector<int>(int *, int *); But if we have const-ness mismatch like std::vector<int>(const int *, const int *); we would use a slow path that copies each element individually. This change enables the optimal specialization for const-ness mismatch. Fixes PR37574.

2019-01-05Fix flaky symlink access time test.Eric Fiselier
last_write_time(sym, new_time) changes the modification time of the file referenced by the symlink. But reading through the symlink may change the symlinks's access time. This meant the previous test that checked that the symlinks access time was unchanged was incorrect and made the test flaky. This patch removes this test (there really is no non-flaky way to test that the new access time coorisponds to the time at which the symlink was last dereferenced). This should unflake the test. llvm-svn: 350478

2018-12-30More tolerance for flaky tests in libc++ on NetBSDKamil Rytarowski
Summary: Tests marked with the flaky attribute ("FLAKY_TEST.") can still report false positives in local tests and on the NetBSD buildbot. Additionally a number of tests (probably all threaded ones) unmarked with the flaky attribute is flaky on NetBSD. An ideal solution on the libcxx side would be to raise max retries for NetBSD and mark failing tests with the flaky flag, however this adds more maintenance burden and constant monitoring of flaky tests. Reduce the work and handle flaky tests as more flaky on NetBSD and allow flakiness of other tests on NetBSD.

2018-12-20[libcxx] Fix order checking in unordered_multimap tests.Louis Dionne
Some tests assume that iteration through an unordered multimap elements will return them in the same order as at the container creation. This assumption is not true since the container is unordered, so that no specific order of elements is ever guaranteed for such container. This patch introduces checks verifying that any iteration will return elements exactly from a set of valid values and without repetition, but in no particular order.
