Dan Gohman 86e1ebf9bb Avoid creating chain dependencies from CopyToReg nodes to load and store ... nodes. This doesn't currently have much impact the generated code, but it does produce simpler-looking SelectionDAGs, and consequently simpler-looking ScheduleDAGs, because there are fewer spurious dependencies. In particular, CopyValueToVirtualRegister now uses the entry node as the input chain dependency for new CopyToReg nodes instead of calling getRoot and depending on the most recent memory reference. Also, rename UnorderedChains to PendingExports and pull it up from being a local variable in SelectionDAGISel::BuildSelectionDAG to being a member variable of SelectionDAGISel, so that it doesn't have to be passed around to all the places that need it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48893 91177308-0d34-0410-b5e6-96231b3b80d8		2008-03-27 19:56:19 +00:00
