This interface allows IRObjectFile to be implemented without having dummy methods for all section and segment related methods. Both llvm-ar and llvm-nm are changed to use it. Unfortunately the mangler is still not plugged in since it requires some refactoring to make a Module hold a DataLayout. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201881 91177308-0d34-0410-b5e6-96231b3b80d8
