| |
| <dl> |
| These options have been replaced with newer versions that use symspecs. |
| |
| <dt><code>-e </code><var>function_name</var><dd>The ‘<samp><span class="samp">-e </span><var>function</var></samp>’ option tells <code>gprof</code> to not print |
| information about the function <var>function_name</var> (and its |
| children<small class="dots">...</small>) in the call graph. The function will still be listed |
| as a child of any functions that call it, but its index number will be |
| shown as ‘<samp><span class="samp">[not printed]</span></samp>’. More than one ‘<samp><span class="samp">-e</span></samp>’ option may be |
| given; only one <var>function_name</var> may be indicated with each ‘<samp><span class="samp">-e</span></samp>’ |
| option. |
| |
| <br><dt><code>-E </code><var>function_name</var><dd>The <code>-E </code><var>function</var> option works like the <code>-e</code> option, but |
| time spent in the function (and children who were not called from |
| anywhere else), will not be used to compute the percentages-of-time for |
| the call graph. More than one ‘<samp><span class="samp">-E</span></samp>’ option may be given; only one |
| <var>function_name</var> may be indicated with each ‘<samp><span class="samp">-E</span></samp>’ option. |
| |
| <br><dt><code>-f </code><var>function_name</var><dd>The ‘<samp><span class="samp">-f </span><var>function</var></samp>’ option causes <code>gprof</code> to limit the |
| call graph to the function <var>function_name</var> and its children (and |
| their children<small class="dots">...</small>). More than one ‘<samp><span class="samp">-f</span></samp>’ option may be given; |
| only one <var>function_name</var> may be indicated with each ‘<samp><span class="samp">-f</span></samp>’ |
| option. |
| |
| <br><dt><code>-F </code><var>function_name</var><dd>The ‘<samp><span class="samp">-F </span><var>function</var></samp>’ option works like the <code>-f</code> option, but |
| only time spent in the function and its children (and their |
| children<small class="dots">...</small>) will be used to determine total-time and |
| percentages-of-time for the call graph. More than one ‘<samp><span class="samp">-F</span></samp>’ option |
| may be given; only one <var>function_name</var> may be indicated with each |
| ‘<samp><span class="samp">-F</span></samp>’ option. The ‘<samp><span class="samp">-F</span></samp>’ option overrides the ‘<samp><span class="samp">-E</span></samp>’ option. |

| <p>Note that only one function can be specified with each <code>-e</code>, |
| <code>-E</code>, <code>-f</code> or <code>-F</code> option. To specify more than one |
| function, use multiple options. For example, this command: |
| |
| <pre class="example"> gprof -e boring -f foo -f bar myprogram > gprof.output |
| </pre> |
| <p class="noindent">lists in the call graph all functions that were reached from either |
| <code>foo</code> or <code>bar</code> and were not reachable from <code>boring</code>. |
