| 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 is 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. |
