Optimal Coalescing with respect to move instruction for Live range splitting

2015-01-17 Thread Ajit Kumar Agarwal
Register allocation with two phase approach does optimal coalescing after the spilling. Sometime Live range splitting makes the coalescing non optimal. The splitted Live range are connected by move instruction. Thus the Live range splitting and more specifically aggressive Live range splitting
