#define __CLANG_CUDA_WRAPPERS_ALGORITHM
// 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>.
#include_next <algorithm>
#if __cplusplus <= 201103L
// We need to define these overloads in exactly the namespace our standard
// library uses (including the right inline namespace), otherwise they won't be
// picked up by other functions in the standard library (e.g. functions in
// <complex>). Thus the ugliness below.
