Using this option 'perf buildid-list' will process all samples, marking the DSOs that had some hits to list just them. This in turn will be used by a new porcelain, 'perf archive', that will be just a shell script to create a tarball from the 'perf buildid-list --with-hits' output and the files cached by 'perf record' in ~/.debug.
