title: Make callgrind show all function calls in the kcachegrind callgraph
body: <p>I was using valgrind tool - callgrind and kcachegrind for profiling a large project and was wondering if there is a way that callgrind reports the stats from all the functions (not just the most expensive functions).</p>
  
  <p>To be specific - When I visualized the callgraph in kcachegrind, it included only those functions that are quite expensive, but I was wondering if there is a way to include all the functions from the project in the callgraph. Command used for generating profiling info is given below : </p>
  
  <pre><code>valgrind --dsymutil=yes --tool=callgrind $EXE 
  </code></pre>
  
  <p>I am not sure if I have to give any options to valgrind or may be compile the application at a different optimization. This might be something trivial but I couldn't find a solution. Any pointers regarding this highly appreciated. </p>
  
  <p>Thanks !</p>
