- 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.
