time.zone.db.access	[libc++] [test] Fix portability issues for MSVC (#93259) * Guard std::__make_from_tuple_impl tests with #ifdef _LIBCPP_VERSION and LIBCPP_STATIC_ASSERT. * Change _LIBCPP_CONSTEXPR_SINCE_CXX20 to TEST_CONSTEXPR_CXX20. + Other functions in variant.swap/swap.pass.cpp were already using the proper test macro. * Mark what as [[maybe_unused]] when used by TEST_LIBCPP_REQUIRE. + This updates one occurrence in libcxx/test/libcxx for consistency. * Windows _putenv_s() takes 2 arguments, not 3. + See MSVC documentation: https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/putenv-s-wputenv-s?view=msvc-170 + POSIX setenv() takes int overwrite, but Windows _putenv_s() always overwrites. * Avoid non-Standard zero-length arrays. + Followup to #74183 and #79792. * Add operator++() to unsized_it. + The Standard requires this due to [N4981][] [move.iter.requirements]/1 "The template parameter Iterator shall either meet the *Cpp17InputIterator* requirements ([input.iterators]) or model input_iterator ([iterator.concept.input])." + MSVC's STL requires this because it has a strengthened exception specification in move_iterator that inspects the underlying iterator's increment operator. * uniform_int_distribution forbids int8_t/uint8_t. + See [N4981][] [rand.req.genl]/1.5. MSVC's STL enforces this. + Note that when changing the distribution's IntType, we need to be careful to preserve the original value range of [0, max_input]. * fstreams are constructible from const fs::path::value_type* on wide systems. + See [ifstream.cons], [ofstream.cons], [fstream.cons]. * In msvc_stdlib_force_include.h, map _HAS_CXX23 to TEST_STD_VER 23 instead of 99. + On 2023-05-23, https://github.com/llvm/llvm-project/commit/71400505ca048507e827013eb1ea0bc863525cab started recognizing 23 as a distinct value. * Fix test name typo: destory_elements.pass.cpp => destroy_elements.pass.cpp [N4981]: https://wg21.link/N4981	2 年前

leap_seconds.pass.cpp	[libc++][chrono] Fixes leap seconds. (#90070) While implementing the UTC clock it turns out that the implementation of the leap seconds was not correct, it should store the individual value, not the sum. It also looks like LWG3359 has not been fully implemented. Implements parts of: - LWG3359 <chrono> leap second support should allow for negative leap seconds	1 年前
