2 | This table describes the call tree of the program, and was sorted by | |
3 | the total amount of time spent in each function and its children. | |
4 | ||
5 | Each entry in this table consists of several lines. The line with the | |
6 | index number at the left hand margin lists the current function. | |
7 | The lines above it list the functions that called this function, | |
8 | and the lines below it list the functions this one called. | |
9 | This line lists: | |
10 | index A unique number given to each element of the table. | |
11 | Index numbers are sorted numerically. | |
12 | The index number is printed next to every function name so | |
13 | it is easier to look up where the function in the table. | |
14 | ||
15 | % time This is the percentage of the `total' time that was spent | |
16 | in this function and its children. Note that due to | |
17 | different viewpoints, functions excluded by options, etc, | |
18 | these numbers will NOT add up to 100%. | |
19 | ||
20 | self This is the total amount of time spent in this function. | |
21 | ||
22 | children This is the total amount of time propagated into this | |
23 | function by its children. | |
24 | ||
25 | called This is the number of times the function was called. | |
26 | If the function called itself recursively, the number | |
27 | only includes non-recursive calls, and is followed by | |
28 | a `+' and the number of recursive calls. | |
29 | ||
30 | name The name of the current function. The index number is | |
31 | printed after it. If the function is a member of a | |
32 | cycle, the cycle number is printed between the | |
33 | function's name and the index number. | |
34 | ||
35 | ||
36 | For the function's parents, the fields have the following meanings: | |
37 | ||
38 | self This is the amount of time that was propagated directly | |
39 | from the function into this parent. | |
40 | ||
41 | children This is the amount of time that was propagated from | |
42 | the function's children into this parent. | |
43 | ||
44 | called This is the number of times this parent called the | |
45 | function `/' the total number of times the function | |
46 | was called. Recursive calls to the function are not | |
47 | included in the number after the `/'. | |
48 | ||
49 | name This is the name of the parent. The parent's index | |
50 | number is printed after it. If the parent is a | |
51 | member of a cycle, the cycle number is printed between | |
52 | the name and the index number. | |
53 | ||
54 | If the parents of the function cannot be determined, the word | |
55 | `<spontaneous>' is printed in the `name' field, and all the other | |
56 | fields are blank. | |
57 | ||
58 | For the function's children, the fields have the following meanings: | |
59 | ||
60 | self This is the amount of time that was propagated directly | |
61 | from the child into the function. | |
62 | ||
63 | children This is the amount of time that was propagated from the | |
64 | child's children to the function. | |
65 | ||
66 | called This is the number of times the function called | |
67 | this child `/' the total number of times the child | |
68 | was called. Recursive calls by the child are not | |
69 | listed in the number after the `/'. | |
70 | ||
71 | name This is the name of the child. The child's index | |
72 | number is printed after it. If the child is a | |
73 | member of a cycle, the cycle number is printed | |
74 | between the name and the index number. | |
75 | ||
76 | If there are any cycles (circles) in the call graph, there is an | |
77 | entry for the cycle-as-a-whole. This entry shows who called the | |
78 | cycle (as parents) and the members of the cycle (as children.) | |
79 | The `+' recursive calls entry shows the number of function calls that | |
80 | were internal to the cycle, and the calls entry for each member shows, | |
81 | for that member, how many times it was called from other members of | |
82 | the cycle. | |
