  53. This table describes the call tree of the program, and was sorted by
  54. the total amount of time spent in each function and its children.
  55. Each entry in this table consists of several lines. The line with the
  56. index number at the left hand margin lists the current function.
  57. The lines above it list the functions that called this function,
  58. and the lines below it list the functions this one called.
  59. This line lists:
  60. index A unique number given to each element of the table.
  61. Index numbers are sorted numerically.
  62. The index number is printed next to every function name so
  63. it is easier to look up where the function in the table.
  64. % time This is the percentage of the `total' time that was spent
  65. in this function and its children. Note that due to
  66. different viewpoints, functions excluded by options, etc,
  67. these numbers will NOT add up to 100%.
  68. self This is the total amount of time spent in this function.
  69. children This is the total amount of time propagated into this
  70. function by its children.
  71. called This is the number of times the function was called.
  72. If the function called itself recursively, the number
  73. only includes non-recursive calls, and is followed by
  74. a `+' and the number of recursive calls.
  75. name The name of the current function. The index number is
  76. printed after it. If the function is a member of a
  77. cycle, the cycle number is printed between the
  78. function's name and the index number.
  79. For the function's parents, the fields have the following meanings:
  80. self This is the amount of time that was propagated directly
  81. from the function into this parent.
  82. children This is the amount of time that was propagated from
  83. the function's children into this parent.
  84. called This is the number of times this parent called the
  85. function `/' the total number of times the function
  86. was called. Recursive calls to the function are not
  87. included in the number after the `/'.
  88. name This is the name of the parent. The parent's index
  89. number is printed after it. If the parent is a
  90. member of a cycle, the cycle number is printed between
  91. the name and the index number.
  92. If the parents of the function cannot be determined, the word
  93. `<spontaneous>' is printed in the `name' field, and all the other
  94. fields are blank.
  95. For the function's children, the fields have the following meanings:
  96. self This is the amount of time that was propagated directly
  97. from the child into the function.
  98. children This is the amount of time that was propagated from the
  99. child's children to the function.
  100. called This is the number of times the function called
  101. this child `/' the total number of times the child
  102. was called. Recursive calls by the child are not
  103. listed in the number after the `/'.
  104. name This is the name of the child. The child's index
  105. number is printed after it. If the child is a
  106. member of a cycle, the cycle number is printed
  107. between the name and the index number.
  108. If there are any cycles (circles) in the call graph, there is an
  109. entry for the cycle-as-a-whole. This entry shows who called the
  110. cycle (as parents) and the members of the cycle (as children.)
  111. The `+' recursive calls entry shows the number of function calls that
  112. were internal to the cycle, and the calls entry for each member shows,
  113. for that member, how many times it was called from other members of
  114. the cycle.
  115. Index by function name
