   1
   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.
