45 * FUNCTION
46 * vector unsigned int _isnanf4(vector float x)

48 * DESCRIPTION
49 * The _isnanf4 function returns a vector in which each element indicates
50 * if the corresponding element of x is NaN.
51 *
52 * On the SPU, this function always returns 0, since NaNs are not
53 * supported.
54 *
55 * RETURNS
56 * UINT_MAX (0xFFFFFFFF) if the element of x is a NaN
57 * 0 (0x00000000) otherwise (always on the SPU)
58 *
