I guess you won't be doing this through clang since you are planning to invoke from ld64, but remember to do this part there for each module being compiled. Will need to do from 'opt' as well for testing. My clang patch also includes support for an option to trigger the pass and pass down the index file path via a CodeGenOption, with corresponding support in llvm to invoke the pass. I can add that part after this goes in.
