I'll make that change. Thanks!
Also (from an early attempt at a cookbook): http://hg.openjdk.java.net/mlvm/mlvm/file/tip/netbeans/indy-demo/src/recipes/FastAndSlow.java This uses the same logic as Remi's safeAdd. What's needed here is a way to get 33 bits out of a 32-bit add intrinsic. There's no fully natural way to do this, and about 4 kludgey ways. Because there are so many poor ways to shape the API, it's hard to pick the best one to invest in. -- John
