| <h4 class="subsection">5.2.3 Lines for a Function's Subroutines</h4> |
| |
| <p>A function's entry has a line for each of its subroutines—in other |
| words, a line for each other function that it called. These lines' |
| fields correspond to the fields of the primary line, but their meanings |
| are different because of the difference in context. |
| |
| <p>For reference, we repeat two lines from the entry for the function |
| <code>main</code>, the primary line and a line for a subroutine, together |
| with the heading line that shows the names of the fields: |
| |
| <pre class="smallexample"> index % time self children called name |
| ... |
| [2] 100.0 0.00 0.05 1 main [2] |
| 0.00 0.05 1/1 report [3] |
| </pre> |
| <p>Here are the meanings of the fields in the subroutine-line for <code>main</code> |
| calling <code>report</code>: |
| |
| <dl> |
| <dt><code>self</code><dd>An estimate of the amount of time spent directly within <code>report</code> |
| when <code>report</code> was called from <code>main</code>. |
| |
| <br><dt><code>children</code><dd>An estimate of the amount of time spent in subroutines of <code>report</code> |
| when <code>report</code> was called from <code>main</code>. |
| |
| <p>The sum of the <code>self</code> and <code>children</code> fields is an estimate |
| of the total time spent in calls to <code>report</code> from <code>main</code>. |
| |
| <br><dt><code>called</code><dd>Two numbers, the number of calls to <code>report</code> from <code>main</code> |
| followed by the total number of non-recursive calls to <code>report</code>. |
| This ratio is used to determine how much of <code>report</code>'s <code>self</code> |
| and <code>children</code> time gets credited to <code>main</code>. |
| See <a href="Assumptions.html#Assumptions">Estimating <code>children</code> Times</a>. |
| |
| <br><dt><code>name</code><dd>The name of the subroutine of <code>main</code> to which this line applies, |
| followed by the subroutine's index number. |
| |
| <p>If the caller is part of a recursion cycle, the cycle number is |
| printed between the name and the index number. |
