You will want to use the pid provider. The most basic thing you can
probably do is to turn on flowindent and just trace
`pid$target:::entry' and `pid$target:::return`, which will trace all
the function calls and returns. This blog post
<http://cuddletech.com/blog/pivot/entry.php?id=923> gives an example
of the script I'm thinking of (this is one of the most basic DTrace
scripts).

Also, you may want to compile at -O0, because DTrace can't instrument
functions that have been inlined.
