> Migrate from using Unsafe to FFM's MemorySegment API for allocating and > setting native memory. > This code is used by Metal, OpenGL and D3D, so I manually tested SwingSet2 > and J2Demo as well as running all the usual tests. > I also did some micro-benchmarking on the performance of Unsafe vs > MemorySegment. > The performance of either is more than sufficient for us .. ie they could be > 10x slower and we wouldn't even notice. > But they are in the same ballpark, and if one or the other is clearly faster > it is the new FFM code.
