variables. This pass can be invoked by llvm-ld or opt to traverse over the call graph to detect what function frames and their automatic variables can be overlaid. Currently this builds an archive , but needs to be changed to a loadable module. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84753 91177308-0d34-0410-b5e6-96231b3b80d8
