I yet have to find a way to get more test coverage - looks like some of the functions aren't used anywhere yet (e.g., VECTOR FP MAXIMUM), writing unit tests to cover all functions and cases is just nasty. But I might be wrong - I'm planning to at least test basic functionality of all new added instructions. I have to make excessive use of c macros again to cover different element sizes (32/64/128bit). Any advise to clean things up are welcome.
