|
||
|
|
|
||
|
|
<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>.
