...for that email. Glad that you put up it again. The approach actually sounds better as it will drastically simplify the back-end code. But I was clueless as to how to make register allocator fold the spills and reloads into the actual target instructions. The only interfaces that it exposes are saveRegToStackSlot and loadRegFromStackSlot, and we didn't even know for which instructions these spills are reloads are happening. All these APIs get is a frameIndex. Now that you have decided to get us to explore a better path, it would be good if you could put more light to these issues. One more thing tha...
