2:
3:
4: call graph profile:
5: The sum of self and descendents is the major sort
6: for this listing.
7:
8: function entries:
9:
10: index the index of the function in the call graph
11: listing, as an aid to locating it (see below).
12:
13: %time the percentage of the total time of the program
14: accounted for by this function and its
15: descendents.
16:
17: self the number of seconds spent in this function
18: itself.
19:
20: descendents
21: the number of seconds spent in the descendents of
22: this function on behalf of this function.
23:
24: called the number of times this function is called (other
25: than recursive calls).
26:
27: self the number of times this function calls itself
28: recursively.
29:
30: name the name of the function, with an indication of
31: its membership in a cycle, if any.
32:
33: index the index of the function in the call graph
34: listing, as an aid to locating it.
35:
36:
37:
38: parent listings:
39:
40: self* the number of seconds of this function's self time
41: which is due to calls from this parent.
42:
43: descendents*
44: the number of seconds of this function's
45: descendent time which is due to calls from this
46: parent.
47:
48: called** the number of times this function is called by
49: this parent. This is the numerator of the
50: fraction which divides up the function's time to
51: its parents.
52:
53: total* the number of times this function was called by
54: all of its parents. This is the denominator of
55: the propagation fraction.
56:
57: parents the name of this parent, with an indication of the
58: parent's membership in a cycle, if any.
59:
60: index the index of this parent in the call graph
61: listing, as an aid in locating it.
62:
63:
64:
65: children listings:
66:
67: self* the number of seconds of this child's self time
68: which is due to being called by this function.
69:
70: descendent*
71: the number of seconds of this child's descendent's
72: time which is due to being called by this
73: function.
74:
75: called** the number of times this child is called by this
76: function. This is the numerator of the
77: propagation fraction for this child.
78:
79: total* the number of times this child is called by all
80: functions. This is the denominator of the
81: propagation fraction.
82:
83: children the name of this child, and an indication of its
84: membership in a cycle, if any.
85:
86: index the index of this child in the call graph listing,
87: as an aid to locating it.
88:
89:
90:
91: * these fields are omitted for parents (or
92: children) in the same cycle as the function. If
93: the function (or child) is a member of a cycle,
94: the propagated times and propagation denominator
95: represent the self time and descendent time of the
96: cycle as a whole.
97:
98: ** static-only parents and children are indicated
99: by a call count of 0.
100:
101:
102:
103: cycle listings:
104: the cycle as a whole is listed with the same
105: fields as a function entry. Below it are listed
106: the members of the cycle, and their contributions
107: to the time and call counts of the cycle.
