Hi, thank you for your explanations. In order to get a pre-RA scheduling, I would need something like: - LiveVars - PhiElim - TwoAddr - LiveIntervals - Coalescing - Scheduler (new) - SlotIndexing - LiveIntervals2 (new) - RegAllocMy qeustion then is, is it really so difficult to create the live intervals information, with modifications to the original algorithm, or even from scratch?
