38 <p>In July 2017, the C++ standard committee created a draft for the next version of the C++ standard, known here as "C++2a" (probably to be C++20).</p>
Stephan T. Lavavejf966d3f2017-08-31 17:59:42 +0000[diff] [blame]39 <p>This page shows the status of libc++; the status of clang's support of the language features is <a href="https://clang.llvm.org/cxx_status.html#cxx2a">here</a>.</p>

This is because the first four algorithms have specializations that call <tt>memmove</tt> which is not constexpr. See <a href="https://bugs.llvm.org/show_bug.cgi?id=25165">Bug 25165</a></p>
