Evan Cheng c6deb3d447 Estimate a cost using the possible number of scratch registers required and use ... it as a late BURR scheduling tie-breaker. Intuitively, it's good to push down instructions whose results are liveout so their long live ranges won't conflict with other values which are needed inside the BB. Further prioritize liveout instructions by the number of operands which are calculated within the BB. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35109 91177308-0d34-0410-b5e6-96231b3b80d8		2007-03-14 22:43:40 +00:00
