NFCI.All supported compilers that support C++20 now support concepts. So, remove`_LIB_LIBCPP_HAS_NO_CONCEPTS` in favor of `_LIBCPP_STD_VER > 17`. Similarly inthe tests, remove `// UNSUPPORTED: libcpp-no-concepts`.Differential Revision: https://reviews.llvm.org/D121528 List of files: /llvm-project-15.0.7/libcxx/test/std/iterators/iterator.primitives/range.iter.ops/range.iter.ops.distance/lwg3664.pass.cpp Sat, 12 Mar 2022 15:46:57 +0000 Joe Loser <joeloser93@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/libcxx/test/std/iterators/iterator.primitives/range.iter.ops/range.iter.ops.distance/lwg3664.pass.cpp#53406fb6 [libc++] Guard much of std::ranges under _LIBCPP_HAS_NO_INCOMPLETE_RANGES.The logic here is that we are disabling *only* things in `std::ranges::`.Everything in `std::` is permitted, including `default_sentinel`, `contiguous_iterator`,`common_iterator`, `projected`, `swappable`, and so on. Then, we includeanything from `std::ranges::` that is required in order to make those thingswork: `ranges::swap`, `ranges::swap_ranges`, `input_range`, `ranges::begin`,`ranges::iter_move`, and so on. But then that's all. Everything else (includingnotably all of the "views" and the `std::views` namespace itself) is stilllocked up behind `_LIBCPP_HAS_NO_INCOMPLETE_RANGES`.Differential Revision: https://reviews.llvm.org/D118736 List of files: /llvm-project-15.0.7/libcxx/test/std/iterators/iterator.primitives/range.iter.ops/range.iter.ops.distance/lwg3664.pass.cpp Tue, 01 Feb 2022 21:52:02 +0000 Arthur O'Dwyer <arthur.j.odwyer@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/libcxx/test/std/iterators/iterator.primitives/range.iter.ops/range.iter.ops.distance/lwg3664.pass.cpp#c965d544 [libc++] [ranges] Implement std::ranges::distanceThis includes an experimental workaround forLWG3664 "LWG3392 broke std::ranges::distance(a, a+3)",but the workaround may be incomplete, I'm not sure.This should be re-audited when LWG3664 is actually adopted,to see if we need to change anything about our implementation.See also https://github.com/microsoft/STL/pull/2500Differential Revision: https://reviews.llvm.org/D117940 List of files: /llvm-project-15.0.7/libcxx/test/std/iterators/iterator.primitives/range.iter.ops/range.iter.ops.distance/lwg3664.pass.cpp Fri, 21 Jan 2022 20:51:46 +0000 Arthur O'Dwyer <arthur.j.odwyer@gmail.com>
