replacing all occurances of this separator in symbol names (and
other output) with a . character, that thus it's the only non
valid separator.
-g [type,min], --call-graph
Display callchains using type and min percent threshold. type can
be either:
o flat: single column, linear exposure of callchains.
o graph: use a graph tree, displaying absolute overhead rates.
o fractal: like graph, but displays relative rates. Each branch
of the tree is considered as a new profiled object.
Default: fractal,0.5.
