| Code: |
!$cuf kernel do <<< *, * >>>
DO I1=2,KK1M2
E0(I1,1)=__int_as_float(iand(__float_as_int(E0(I1,1)),__float_as_int(X0(I1,1))))
END DO

I'm trying to use __int_as_float function in kernel loop region. Comiler says:

module cudadevice is included in subroutine. Why does this functions is not allowed in kernel loop region, but allowed in device subroutines? |

In order to support these in kernel loop, host and other device versions would needed to be developed since kernels can target multiple devices as well as the host.
