Andrew Trick 3eb4319313 PreRA scheduler heuristic fixes: VRegCycle, TokenFactor latency. ... 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 these heuristic adjustments to node latency 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@129383 91177308-0d34-0410-b5e6-96231b3b80d8		2011-04-12 19:54:36 +00:00
