Andrew Trick 3b87f6204f misched: Heuristics based on the machine model. ... misched is disabled by default. With -enable-misched, these heuristics balance the schedule to simultaneously avoid saturating processor resources, expose ILP, and minimize register pressure. I've been analyzing the performance of these heuristics on everything in the llvm test suite in addition to a few other benchmarks. I would like each heuristic check to be verified by a unit test, but I'm still trying to figure out the best way to do that. The heuristics are still in considerable flux, but as they are refined we should be rigorous about unit testing the improvements. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167527 91177308-0d34-0410-b5e6-96231b3b80d8		2012-11-07 07:05:09 +00:00
