Chandler Carruth fa97658b1c Begin chipping away at one of the biggest quadratic-ish behaviors in ... this pass. We're leaving already merged blocks on the worklist, and scanning them again and again only to determine each time through that indeed they aren't viable. We can instead remove them once we're going to have to scan the worklist. This is the easy way to implement removing them. If this remains on the profile (as I somewhat suspect it will), we can get a lot more clever here, as the worklist's order is essentially irrelevant. We can use swapping and fold the two loops to reduce overhead even when there are many blocks on the worklist but only a few of them are removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144531 91177308-0d34-0410-b5e6-96231b3b80d8		2011-11-14 09:46:33 +00:00
