| |
| <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>. |
