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. | |
