|
||
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.
