This option is added by Xcode when it runs the linker. It produces a binary file which contains the file the linker used. Xcode uses the info to dynamically update it dependency tracking. To check the content of the binary file, the test case uses a python script to dump the binary file as text which FileCheck can check. llvm-svn: 219039
