This table describes the call tree of the program, and was sorted by
|
|
|
|
|
|
the total amount of time spent in each function and its children.
|
|
|
|
|
|
|
|
|
|
|
|
Each entry in this table consists of several lines. The line with the
|
|
|
|
|
|
index number at the left hand margin lists the current function.
|
|
|
|
|
|
The lines above it list the functions that called this function,
|
|
|
|
|
|
and the lines below it list the functions this one called.
|
|
|
|
|
|
This line lists:
|
|
|
|
|
|
index A unique number given to each element of the table.
|
|
|
|
|
|
Index numbers are sorted numerically.
|
|
|
|
|
|
The index number is printed next to every function name so
|
|
|
|
|
|
it is easier to look up where the function in the table.
|
|
|
|
|
|
|
|
|
|
|
|
% time This is the percentage of the `total' time that was spent
|
|
|
|
|
|
in this function and its children. Note that due to
|
|
|
|
|
|
different viewpoints, functions excluded by options, etc,
|
|
|
|
|
|
these numbers will NOT add up to 100%.
|
|
|
|
|
|
|
|
|
|
|
|
self This is the total amount of time spent in this function.
|
|
|
|
|
|
|
|
|
|
|
|
children This is the total amount of time propagated into this
|
|
|
|
|
|
function by its children.
|
|
|
|
|
|
|
|
|
|
|
|
called This is the number of times the function was called.
|
|
|
|
|
|
If the function called itself recursively, the number
|
|
|
|
|
|
only includes non-recursive calls, and is followed by
|
|
|
|
|
|
a `+' and the number of recursive calls.
|
|
|
|
|
|
|
|
|
|
|
|
name The name of the current function. The index number is
|
|
|
|
|
|
printed after it. If the function is a member of a
|
|
|
|
|
|
cycle, the cycle number is printed between the
|
|
|
|
|
|
function's name and the index number.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
For the function's parents, the fields have the following meanings:
|
|
|
|
|
|
|
|
|
|
|
|
self This is the amount of time that was propagated directly
|
|
|
|
|
|
from the function into this parent.
|
|
|
|
|
|
|
|
|
|
|
|
children This is the amount of time that was propagated from
|
|
|
|
|
|
the function's children into this parent.
|
|
|
|
|
|
|
|
|
|
|
|
called This is the number of times this parent called the
|
|
|
|
|
|
function `/' the total number of times the function
|
|
|
|
|
|
was called. Recursive calls to the function are not
|
|
|
|
|
|
included in the number after the `/'.
|
|
|
|
|
|
|
|
|
|
|
|
name This is the name of the parent. The parent's index
|
|
|
|
|
|
number is printed after it. If the parent is a
|
|
|
|
|
|
member of a cycle, the cycle number is printed between
|
|
|
|
|
|
the name and the index number.
|
|
|
|
|
|
|
|
|
|
|
|
If the parents of the function cannot be determined, the word
|
|
|
|
|
|
`<spontaneous>' is printed in the `name' field, and all the other
|
|
|
|
|
|
fields are blank.
|
|
|
|
|
|
|
|
|
|
|
|
For the function's children, the fields have the following meanings:
|
|
|
|
|
|
|
|
|
|
|
|
self This is the amount of time that was propagated directly
|
|
|
|
|
|
from the child into the function.
|
|
|
|
|
|
|
|
|
|
|
|
children This is the amount of time that was propagated from the
|
|
|
|
|
|
child's children to the function.
|
|
|
|
|
|
|
|
|
|
|
|
called This is the number of times the function called
|
|
|
|
|
|
this child `/' the total number of times the child
|
|
|
|
|
|
was called. Recursive calls by the child are not
|
|
|
|
|
|
listed in the number after the `/'.
|
|
|
|
|
|
|
|
|
|
|
|
name This is the name of the child. The child's index
|
|
|
|
|
|
number is printed after it. If the child is a
|
|
|
|
|
|
member of a cycle, the cycle number is printed
|
|
|
|
|
|
between the name and the index number.
|
|
|
|
|
|
|
|
|
|
|
|
If there are any cycles (circles) in the call graph, there is an
|
|
|
|
|
|
entry for the cycle-as-a-whole. This entry shows who called the
|
|
|
|
|
|
cycle (as parents) and the members of the cycle (as children.)
|
|
|
|
|
|
The `+' recursive calls entry shows the number of function calls that
|
|
|
|
|
|
were internal to the cycle, and the calls entry for each member shows,
|
|
|
|
|
|
for that member, how many times it was called from other members of
|
|
|
|
|
|
the cycle.
