call graph profile:
The sum of self and descendents is the major sort
for this listing.
function entries:
index the index of the function in the call graph
listing, as an aid to locating it (see below).
%time the percentage of the total time of the program
accounted for by this function and its
descendents.
self the number of seconds spent in this function
itself.
descendents
the number of seconds spent in the descendents of
this function on behalf of this function.
called the number of times this function is called (other
than recursive calls).
self the number of times this function calls itself
recursively.
name the name of the function, with an indication of
its membership in a cycle, if any.
index the index of the function in the call graph
listing, as an aid to locating it.
parent listings:
self* the number of seconds of this function's self time
which is due to calls from this parent.
descendents*
the number of seconds of this function's
descendent time which is due to calls from this
parent.
called** the number of times this function is called by
this parent. This is the numerator of the
fraction which divides up the function's time to
its parents.
total* the number of times this function was called by
all of its parents. This is the denominator of
the propagation fraction.
parents the name of this parent, with an indication of the
parent's membership in a cycle, if any.
index the index of this parent in the call graph
listing, as an aid in locating it.
children listings:
self* the number of seconds of this child's self time
which is due to being called by this function.
descendent*
the number of seconds of this child's descendent's
time which is due to being called by this
function.
called** the number of times this child is called by this
function. This is the numerator of the
propagation fraction for this child.
total* the number of times this child is called by all
functions. This is the denominator of the
propagation fraction.
children the name of this child, and an indication of its
membership in a cycle, if any.
index the index of this child in the call graph listing,
as an aid to locating it.
* these fields are omitted for parents (or
children) in the same cycle as the function. If
the function (or child) is a member of a cycle,
the propagated times and propagation denominator
represent the self time and descendent time of the
cycle as a whole.
** static-only parents and children are indicated
by a call count of 0.
cycle listings:
the cycle as a whole is listed with the same
fields as a function entry. Below it are listed
the members of the cycle, and their contributions
to the time and call counts of the cycle.
