<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
