[libc++] [P1518R2] Better CTAD behavior for containers with allocators. P1518 does the following in C++23 but we'll just do it in C++17 as well: - Stop requiring `Alloc` to be an allocator on some container-adaptor deduction guides - Stop deducing from `Allocator` on some sequence container constructors - Stop deducing from `Allocator` on some other container constructors (libc++ already did this) The affected constructors are the "allocator-extended" versions of constructors where the non-allocator arguments are already sufficient to deduce the allocator type.

[libc++] Include revision numbers in the paper status lists Several of our C++20 and C++2b papers were missing the actual revision number that was voted in to the Standard. The revision number is quite important because in a few cases, a paper has a revision *after* the one that is voted into the Standard, which isn't voted into the Standard. Hence, if we simply followed the wg21.link blindly and implemented that, we'd end up implementing the latest revision of the paper, which might not have been voted. As a fly-by fix, I found out that P1664 had been withdrawn from the straw polls and had never been voted into the Standard. This commit removes that entry from our list.

[libc++] [ranges] Introduce _LIBCPP_AUTO_CAST(x) for auto(x). Clang is gaining `auto(x)` support in D113393; sadly there seems to be no feature-test macro for it. Zhihao is opening a core issue for that macro. Use `_LIBCPP_AUTO_CAST` where C++20 specifies we should use `auto(x)`; stop using `__decay_copy(x)` in those places. In fact, remove `__decay_copy` entirely. As of C++20, it's purely a paper specification tool signifying "Return just `x`, but it was perfect-forwarded, so we understand you're going to have to call its move-constructor sometimes." I believe there's no reason we'd ever need to do its operation explicitly in code. This heisenbugs away a test failure on MinGW; see D112214. Differential Revision: https://reviews.llvm.org/D115686

[libc++][ranges] P2387R3: Pipe support for user-defined range adaptors (#89148) This patch finalizes the std::ranges::range_adaptor_closure class template from https://wg21.link/P2387R3. // [range.adaptor.object], range adaptor objects template<class D> requires is_class_v<D> && same_as<D, remove_cv_t<D>> class range_adaptor_closure { }; The current implementation of __range_adaptor_closure was introduced in ee44dd8062a26541808fc0d3fd5c6703e19f6016 and has served as the foundation for the range adaptors in libc++ for a while. This patch keeps its implementation, with the exception of the following changes: - __range_adaptor_closure now includes the missing constraints `is_class_v<D> && same_as<D, remove_cv_t<D>>` to restrict the type of class that can inherit from it. (https://eel.is/c++draft/ranges.syn) - The operator| of __range_adaptor_closure no longer requires its first argument to model viewable_range. (https://eel.is/c++draft/range.adaptor.object#1) - The _RangeAdaptorClosure concept is refined to exclude cases where T models range or where T has base classes of type range_adaptor_closure<U> for another type U.

This paper does not perform this relaxation, as the copy constructibility requirement is enshrined in the indirect callable concepts ([indirectcallable.indirectinvocable]). Thus, while this paper modifies the views that currently use copyable-box for user provided predicates, it only does so to apply the rename of the exposition-only type to movable-box; it does not change any of the constraints on those views. It does, however, relax the requirements on invocables accepted by the transform family of views, because those are not constrained using the indirect callable concepts. ``` Reviewed By: #libc, var-const Differential Revision: https://reviews.llvm.org/D151629

[libc++][ranges] P2609R3: Relaxing Ranges Just A Smidge (#101715) This patch implements https://wg21.link/p2609r3. The test code was originally authored by JMazurkiewicz. Notes: - P2609R3 is not officially a Defect Report, but MSVC STL implements it in C++20 mode. Moreover, P2609R3 and P2997R1 touch exactly the same set of concepts, and MSVC STL and libc++ have already treated P2997R1 as a DR. - This patch also adjusted feature-test macros. + In C++20 mode, the value of __cpp_lib_ranges should be `202110L` because - `202202L` covers `range_adaptor_closure` (P2387R3), and - `202207L` covers move-only types in range adaptors (P2494R2). And all of these changes are only available since C++23 mode. + In C++23 mode, the value should be `202406L` because - `202211L` covers removing poison overloads (P2602R2), - `202302L` covers relaxing projected value types (P2609R3), and - `202406L` covers removing requirements on `iter_common_reference_t` (P2997R1). And all of these changes are already or being implemented. Fixes #105253. Co-authored-by: Jakub Mazurkiewicz <mazkuba3@gmail.com>

[libc++][format] Improves escaping. (#88283) The change increments the size of the lookup table considerably. The table has an "upper boundary" check. The removal of the code units with the property Grapheme_Extend=Yes removes the range E0100..E01EF. This breaks the trailing large continuous section in two parts. This will be improved in a followup patch.

[libc++][format] Improves width estimate. As obvious from the paper's title this is an LWG issue and thus retroactively applied to C++20. This change may the output for certain code points: 1 Considers 8477 extra codepoints as having a width 2 (as of Unicode 15) (mostly Tangut Ideographs) 2 Change the width of 85 unassigned code points from 2 to 1 3 Change the width of 8 codepoints (in the range U+3248 CIRCLED NUMBER TEN ON BLACK SQUARE ... U+324F CIRCLED NUMBER EIGHTY ON BLACK SQUARE) from 2 to 1, because it seems questionable to make an exception for those without input from Unicode Note that libc++ already uses Unicode 15, while the Standard requires Unicode 12. (The last time I checked MSVC STL used Unicode 14.) So in practice the only notable change is item 3.
