   The lines full of dashes divide this table into "entries", one for
each function.  Each entry has one or more lines.

   In each entry, the primary line is the one that starts with an index
number in square brackets.  The end of this line says which function the
entry is for.  The preceding lines in the entry describe the callers of
this function and the following lines describe its subroutines (also
called "children" when we speak of the call graph).

   The entries are sorted by time spent in the function and its
subroutines.

   The internal profiling function 'mcount' (*note The Flat Profile:
Flat Profile.) is never mentioned in the call graph.

* Primary::       Details of the primary line's contents.
* Callers::       Details of caller-lines' contents.
* Subroutines::   Details of subroutine-lines' contents.
* Cycles::        When there are cycles of recursion,
                   such as 'a' calls 'b' calls 'a'...
