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.
