numeric.iota	[libc++] Remove test-suite annotations for unsupported Clang versions Differential Revision: https://reviews.llvm.org/D108471	4 年前
numeric.ops.gcd	[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
numeric.ops.lcm	[libc++] Fix incorrect overflow checking in std::lcm (#96310) We should have been using __builtin_mul_overflow from the start instead of adding a manual (and error-prone) check for overflow. Fixes #96196	2 年前
numeric.ops.midpoint	[libc++] Some tests are missing include for `numeric_limits` (#90345) Noticed while attempting microsoft/STL#4634	2 年前
numeric.ops.sat	[libc++] Fix one case in saturate_cast.pass.cpp for 64-bit on z/OS (#86724) On z/OS int128 is disabled causing one of the cases in `saturate_cast.pass.cpp` to fail. The failure is only in 64-bit mode. In this case `the std::numeric_limits<long long int>::max()` is within `std::numeric_limits<unsigned long int>::min()` and `std::numeric_limits<unsigned long int>::max()` therefore, saturate_cast<unsigned long int>( sBigMax) == LONG_MAX and not ULONG_MAX as original test. In 32-bit, `saturate_cast<unsigned long int>( sBigMax) == ULONG_MAX` like on other platforms where int128 is enabled. This PR is required to pass this test case on z/OS and possibly on other platforms where int128 is not supported/enabled. --------- Co-authored-by: Sean Perry <perry@ca.ibm.com>	2 年前

reduce	[libc++][pstl] Improve exception handling (#88998) There were various places where we incorrectly handled exceptions in the PSTL. Typical issues were missing `noexcept` and taking iterators by value instead of by reference. This patch fixes those inconsistent and incorrect instances, and adds proper tests for all of those. Note that the previous tests were often incorrectly turned into no-ops by the compiler due to copy ellision, which doesn't happen with these new tests.	2 年前
