.It Fl b
Suppress the printing of a description of each field in the profile.
.It Fl c
The static call graph of the program is discovered by a heuristic
that examines the text space of the object file.
Static-only parents or children are shown
with call counts of 0.
This option is not supported on some architectures.
.It Fl C Ar count
Find a minimal set of arcs that can be broken to eliminate all cycles with
