// Unlike OpenCL, HIP depends on the C++ interpration of "unsigned long", which
// is 64 bits long on Linux and 32 bits long on Windows. The return type of the
// ballot intrinsic needs to be a 64 bit integer on both platforms. This test
// cross-compiles to Windows to confirm that the return type is indeed 64 bits
// on Windows.
