Marshall Clow	af552ba05a	Implement P0599: 'noexcept for hash functions'. Fix a couple of hash functions (optional<T> and unique_ptr<T>) which were mistakenly marked as 'noexcept'. Reviewed as https://reviews.llvm.org/D31234 ... git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@298573 91177308-0d34-0410-b5e6-96231b3b80d8	2017-03-23 02:40:28 +00:00
Eric Fiselier	952eaecfc6	Implement P0513R0 - "Poisoning the Hash" ... Summary: Exactly what the title says. This patch also adds a `std::hash<nullptr_t>` specialization in C++17, but it was not added by this paper and I can't find the actual paper that adds it. See http://wg21.link/P0513R0 for more info. If there are no comments in the next couple of days I'll commit this Reviewers: mclow.lists, K-ballo, EricWF Reviewed By: EricWF Subscribers: cfe-commits Differential Revision: https://reviews.llvm.org/D28938 git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@292684 91177308-0d34-0410-b5e6-96231b3b80d8	2017-01-21 00:02:12 +00:00
Marshall Clow	674e07d3c8	libc++ implements its' hash objects as deriving from std::unary_function, and the tests test for that. STL @ MS pointed out that the standard doesn't requie these objects to derive from unary_function, and so the tests should not require that either. Change the tests to check for the embedded typedefs - which ARE required. No change to the library. ... git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@225403 91177308-0d34-0410-b5e6-96231b3b80d8	2015-01-07 21:53:23 +00:00
