Дмитрий Изволов	69b54c1a05	[libcxx][algorithm] Optimize std::stable_sort via radix sort algorithm (#104683 ) The radix sort (LSD) algorithm allows to speed up std::stable_sort dramatically in case we sort integers. The speed up varies from a relatively small to x10 times, depending on type of sorted elements and the initial state of the sorted array. ``` Running ./libcxx/test/benchmarks/stable_sort.bench.out Run

David Benjamin	bcf9fb9802	[libc++][hardening] Use bounded iterators in std::vector and std::string (#78929 ) ~~NB: This PR depends on #78876. Ignore the first commit when reviewing, and don't merge it until #78876 is resolved. When/if #78876 lands, I'll clean this up.~~ This partially restores parity with the old, since removed debug build. We now can re-enable a bunch of the disabled tests. Some things of note: - `bounded_iter`'s converting constructor has never worked. It needs a friend declaration to access the other `bound_iter` instantiation's private fields. - The old debug iterators also checked that callers did not try to compare iterators from different objects. `bounded_iter` does not currently do this, so I've left those disabled. However, I think we probably should add those. See https://github.com/llvm/llvm-project/issues/78771#issuecomment-1902999181 - The `std::vector` iterators are bounded up to capacity, not size. This makes for a weaker safety check. This is because the STL promises not to invalidate iterators when appending up to the capacity. Since we cannot retroactively update all the iterators on `push_back()`, I've instead sized it to the capacity. This is not as good, but at least will stop the iterator from going off the end of the buffer. There was also no test for this, so I've added one in the `std` directory. - `std::string` has two ambiguities to deal with. First, I opted not to size it against the capacity. https://eel.is/c++draft/string.require#4 says iterators are invalidated on an non-const operation. Second, whether the iterator can reach the NUL terminator. The previous debug tests and the special-case in https://eel.is/c++draft/string.access#2 suggest no. If either of these causes widespread problems, I figure we can revisit. - `resize_and_overwrite.pass.cpp` assumed `std::string`'s iterator supported `s.begin().base()`, but I see no promise of this in the standard. GCC also doesn't support this. I fixed the test to use `std::to_address`. - `alignof.compile.pass.cpp`'s pointer isn't enough of a real pointer. (It needs to satisfy `NullablePointer`, `LegacyRandomAccessIterator`, and `LegacyContiguousIterator`.) `__bounded_iter` seems to instantiate enough to notice. I've added a few more bits to satisfy it. Fixes #78805	2024-07-22 22:44:25 -07:00

Iuri Chaer	a0662176a9	[libc++] Speed up set_intersection() by fast-forwarding over ranges of non-matching elements with one-sided binary search. (#75230 ) One-sided binary search, aka meta binary search, has been in the public domain for decades, and has the general advantage of being constant time in the best case, with the downside of executing at most 2log(N) comparisons vs classic binary search's exact log(N). There are two scenarios in which it really shines: the first one is when operating over non-random-access iterators, because the classic algorithm requires knowing the container's size upfront, which adds N iterator increments to the complexity. The second one is when traversing the container in order, trying to fast-forward to the next value: in that case the classic algorithm requires at least O(Nlog(N)) comparisons and, for non-random-access iterators, O(N^2) iterator increments, whereas the one-sided version will yield O(N) operations on both counts, with a best-case of O(log(N)) comparisons which is very common in practice.	2024-07-18 16:11:24 -04:00

Louis Dionne	81955da03b	[libc++] Remove special handling of the native C++ library in benchmarks (#98529 ) There were some ad-hoc settings that allowed running the benchmarks against the native C++ Standard Library. While this ability is very useful, it was done before the test suite was quite independent of libc++ itself. Instead, it is better to streamline running the benchmarks on the native standard library by using a custom Lit configuration like we do with the test suite. A follow-up patch will rework the integration of benchmarks with the Lit configuration used for the test suite so that we can reuse the same mechanism for both, making it easy to benchmark the native standard library. It will also make benchmarks way more user-friendly to run since we will be able to run them like we run individual tests, which is a pain point right now.	2024-07-17 13:20:48 -04:00

Louis Dionne	ef51e617c4	[libc++] Handle _LIBCPP_HAS_NO_{THREADS,LOCALIZATION} consistently with other carve-outs (#98319 ) Previously, we would issue an #error when using a header that requires threading support or localization support in a configuration where that is disabled. This is unlike what we do for all the other carve outs like no-filesystem, no-wide-characters or no-random-device. Instead of issuing an #error, we normally just remove the problematic parts of the header. This patch makes the handling of no-localization and no-threads consistent with the other carve-outs. I dislike the fact that users won't get an explicit error message when trying to use e.g. ios in a build that doesn't support localization, but I think it is better to handle things consistently. Note that besides the consistency argument, the #error approach doesn't really work anyways since it would break down if we moved towards assuming the C locale only in the no-localization mode.	2024-07-15 10:11:23 -04:00

Louis Dionne	9ddedf07ed	[libc++] Deprecate the C++20 synchronization library before C++20 (#86410 ) When we initially implemented the C++20 synchronization library, we reluctantly accepted for the implementation to be backported to C++03 upon request from the person who provided the patch. This was when we were only starting to have experience with the issues this can create, so we flinched. Nowadays, we have a much stricter stance about not backporting features to previous standards. We have recently started fixing several bugs (and near bugs) in our implementation of the synchronization library. A recurring theme during these reviews has been how difficult to understand the current code is, and upon inspection it becomes clear that being able to use a few recent C++ features (in particular lambdas) would help a great deal. The code would still be pretty intricate, but it would be a lot easier to reason about the flow of callbacks through things like __thread_poll_with_backoff. As a result, this patch deprecates support for the synchronization library before C++20. In the next release, we can remove that support entirely.	2024-04-16 10:57:48 -04:00

Xiaoyang Liu	7cafe04e0d	[libc++] P3029R1: Better `mdspan`'s CTAD (#87873 ) ## Abstract This pull request implements [P3029R1](https://wg21.link/P3029R1). The paper discusses the current behavior of `mdspan`'s most common pointer-indices CTAD, where the `Extents` template parameter is deduced as `dextents` (dynamic extents), even when passing compile-time constant values. The author believes this behavior is suboptimal, as it doesn't take advantage of the compile-time information. The proposed change suggests deducing static extents if `integral_constant`-like constants are passed, resulting in more intuitive syntax and less error-prone code. ## Reference - [P3029R1](https://wg21.link/P3029R1) - [Draft C++ Standard: [span.syn]](https://eel.is/c++draft/span.syn) - [Draft C++ Standard: [mdspan.syn]](https://eel.is/c++draft/mdspan.syn)	2024-04-12 19:25:22 +02:00
Mark de Wever	59e66c515a	[libc++][format] Switches to Unicode 15.1. (#86543 ) In addition to changes in the tables the extended grapheme clustering algorithm has been overhauled. Before I considered a separate state machine to implement the rules. With the new rule GB9c this became more attractive and the design has changed. This change initially had quite an impact on the performance. By making the state machine persistent the performance was improved greatly. Note it is still slower than before due to the larger Unicode tables.

Ilya Biryukov	4bf8dc1a0f	[libc++] Remove macros for keeping std::allocator members and void specialization after C++20 (#85806 ) Fixes #75975. Remove `_LIBCPP_ENABLE_CXX20_REMOVED_ALLOCATOR_MEMBERS` for the LLVM 19 release, it was previously marked as deprecated in LLVM 18. I believe that `_LIBCPP_ENABLE_CXX20_REMOVED_ALLOCATOR_VOID_SPECIALIZATION` was only used by Google in conjunction with `_LIBCPP_ENABLE_CXX20_REMOVED_ALLOCATOR_MEMBERS`. Removing both macros together should not cause any issues in practice, even though we did not announce the removal of `_LIBCPP_ENABLE_CXX20_REMOVED_ALLOCATOR_VOID_SPECIALIZATION` before.	2024-03-21 17:48:13 +01:00
