--dump-raw-trace::
Dump raw trace in ASCII.
-g [type,min,order]::
-g [type,min[,limit],order]::
--call-graph::
Display call chains using type, min percent threshold and order.
Display call chains using type, min percent threshold, optional print
limit and order.
type can be either:
- flat: single column, linear exposure of call chains.
- graph: use a graph tree, displaying absolute overhead rates.
