15// This file forward-declares of some math functions we (or the CUDA headers)
16// will define later. We need to do this, and do it before cmath is included,
17// because the standard library may have constexpr math functions. In the
18// absence of a prior __device__ decl, those constexpr functions may become
19// implicitly host+device. host+device functions can't be overloaded, so that
20// would preclude the use of our own __device__ overloads for these functions.
