Dan Gohman 002b44f1d7 Add a pre-pass to the burr-list scheduler which makes adjustments to ... help out the register pressure reduction heuristics in the case of nodes with multiple uses. Currently this uses very conservative heuristics, so it doesn't have a broad impact, but in cases where it does help it can make a big difference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67586 91177308-0d34-0410-b5e6-96231b3b80d8		2009-03-24 00:49:12 +00:00
