Converting a vector of floats (via a cast) to a vector of ints of the same size uses a VIEW_CONVERT_EXPR, so the data are simply copied, not converted. This is different from a cast from scalar float to int, where a conversion is performed.From what I can see of the source, this is deliberate.
The short answer is that AltiVec dictated this behavior. :-( Longer answers were given by Ian and Paul, and I agree with them.
