I think you need to use llvm-readobj/FileCheck after each call to check the output file. Otherwise, this does nothing other than check that llvm-objcopy understands the value (but it might do absolutely nothing with it, for example). Once you do that, you should probably use a separate output file, so that you're not modifying the input in place, messing it up for other executions in the same test.
