Ok, good. The rather old opt ref manual that I had didn't cover these. The one I downloaded this afternoon does. And it seems that we would need new costs fields to properly model the more recent intel cpus. I don't suppose I could convince you or your cohorts to add some new fields to the cost struct to handle vector integer operations? Prolly only need logical and mult? r~
