This has led to many test suite failures because of copy and paste where new test cases were based off of other test cases and the "mydir" variable wasn't updated. Now you can call your superclasses "compute_mydir()" function with "__file__" as the sole argument and the relative path will be computed for you. llvm-svn: 196985
