| <h2 class="chapter">5 Interpreting <code>gprof</code>'s Output</h2> |
| |
| <p><code>gprof</code> can produce several different output styles, the |
| most important of which are described below. The simplest output |
| styles (file information, execution count, and function and file ordering) |
| are not described here, but are documented with the respective options |
| that trigger them. |
| See <a href="Output-Options.html#Output-Options">Output Options</a>. |
| |
| <ul class="menu"> |
| <li><a accesskey="1" href="Flat-Profile.html#Flat-Profile">Flat Profile</a>: The flat profile shows how much time was spent |
| executing directly in each function. |
| <li><a accesskey="2" href="Call-Graph.html#Call-Graph">Call Graph</a>: The call graph shows which functions called which |
| others, and how much time each function used |
| when its subroutine calls are included. |
| <li><a accesskey="3" href="Line_002dby_002dline.html#Line_002dby_002dline">Line-by-line</a>: <code>gprof</code> can analyze individual source code lines |
| <li><a accesskey="4" href="Annotated-Source.html#Annotated-Source">Annotated Source</a>: The annotated source listing displays source code |
| labeled with execution counts |
| </ul> |
