Jakob Stoklund Olesen cc07e04262 Reverse order of RS_Split live ranges under -compact-regions. There are two conflicting strategies in play: - Under high register pressure, we want to assign large live ranges first. Smaller live ranges are easier to place afterwards. - Live range splitting is guided by interference, so splitting should be deferred until interference is as realistic as possible. With the recent changes to the live range stages, and with compact regions enabled, it is less traumatic to split a live range too early. If some of the split products were too big, they can often be split again. By reversing the RS_Split order, we get this queue order: 1. Normal live ranges, large to small. 2. RS_Split live ranges, large to small. The large-to-small order improves RAGreedy's puzzle solving skills under high register pressure. It may cause a bit more iterated splitting, but we handle that better now. With this change, -compact-regions is mostly an improvement on SPEC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136388 91177308-0d34-0410-b5e6-96231b3b80d8		2011-07-28 20:48:23 +00:00
