f9127593a9
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 llvm-svn: 292684
