I, for one, would love to see us try using the native stack register for reasons entirely separate from performance. Namely, it would make using existing debugging and performance analysis tools (e.g. perf) much easier. I believe that Andreas Klebinger has also suggested moving return point info tables away from code. It would be interesting to get an estimate of the size of this effect on performance. Cheers, - Ben
