Unless we meet an insertvalue on a path from some value to a return, that value will be live if *any* of the return's components are live, so all of those components must be added to the MaybeLiveUses. Previously we were deleting arguments if sub-value 0 turned out to be dead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@228731 91177308-0d34-0410-b5e6-96231b3b80d8
