Nikolas Klauser	7afa1598a3	[libc++] Avoid including <tuple> in compressed_pair.h ... compressed_pair is widely used in the library, but most of the uses don't use the tuple parts. To avoid including <tuple> everywhere, use the forward declaration instead in compressed_pair.h Reviewed By: ldionne, #libc Spies: libcxx-commits Differential Revision: https://reviews.llvm.org/D133331	2022-09-18 10:49:35 +02:00
Joe Loser	d2baefae68	[libc++] Replace _LIBCPP_HAS_NO_CONCEPTS with _LIBCPP_STD_VER > 17. 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 in the tests, remove `// UNSUPPORTED: libcpp-no-concepts`.
