+// This header defines __device__ overloads of std::min/max, but only if we're
+// <= C++11.  In C++14, these functions are constexpr, and so are implicitly
+// __host__ __device__.
+//
+// We don't support the initializer_list overloads because
+// initializer_list::begin() and end() are not __host__ __device__ functions.
+//
+// When compiling in C++14 mode, we could force std::min/max to have different
+// implementations for host and device, by declaring the device overloads
+// before the constexpr overloads appear.  We choose not to do this because
+
+//  a) why write our own implementation when we can use one from the standard
+//     library? and
+//  b) libstdc++ is evil and declares min/max inside a header that is included
+//     *before* we include <algorithm>.  So we'd have to unconditionally
+//     declare our __device__ overloads of min/max, but that would pollute
+//     things for people who choose not to include <algorithm>.
