Andrew Trick 87896d9368 Recommit r129383. PreRA scheduler heuristic fixes: VRegCycle, TokenFactor latency. ... Additional fixes: Do something reasonable for subtargets with generic itineraries by handle node latency the same as for an empty itinerary. Now nodes default to unit latency unless an itinerary explicitly specifies a zero cycle stage or it is a TokenFactor chain. Original fixes: UnitsSharePred was a source of randomness in the scheduler: node priority depended on the queue data structure. I rewrote the recent VRegCycle heuristics to completely replace the old heuristic without any randomness. To make the ndoe latency adjustments work, I also needed to do something a little more reasonable with TokenFactor. I gave it zero latency to its consumers and always schedule it as low as possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129421 91177308-0d34-0410-b5e6-96231b3b80d8		2011-04-13 00:38:32 +00:00
