title: display only source code with Perf annotate
body: <p>I'm using Perf to perform some profiling experiments.</p>
  <p>However, I would like to know results for a specific code region and for this case seeing the results (percentages) for each line of source code (C/C++ in this case) would ease the task.</p>
  <p><code>perf annotate</code> <a href="https://perf.wiki.kernel.org/index.php/Tutorial#Source_level_analysis_with_perf_annotate" rel="nofollow noreferrer">has a view</a> where it displays ASM+Source Code and also has the option to turn off showing source code. I would like to know how to accomplish the other end of this option, that is, showing only Source Code + its percentages of events per line and hide ASM output. Is this possible with <code>perf</code>?</p>
  <p>Suggestion of other tool to do that? I'm also using Vtune however the analysis I want to do not is working. Valgrind is out of question, too slow.</p>
  <p>I'm on an x64 running Ubuntu 13.04.</p>
