  191. This table describes the call tree of the program, and was sorted by
  192. the total amount of time spent in each function and its children.
  193.  
  194. Each entry in this table consists of several lines. The line with the
  195. index number at the left hand margin lists the current function.
  196. The lines above it list the functions that called this function,
  197. and the lines below it list the functions this one called.
  198. This line lists:
  199. index A unique number given to each element of the table.
  200. Index numbers are sorted numerically.
  201. The index number is printed next to every function name so
  202. it is easier to look up where the function in the table.
  203.  
  204. % time This is the percentage of the `total' time that was spent
  205. in this function and its children. Note that due to
  206. different viewpoints, functions excluded by options, etc,
  207. these numbers will NOT add up to 100%.
  208.  
  209. self This is the total amount of time spent in this function.
  210.  
  211. children This is the total amount of time propagated into this
  212. function by its children.
  213.  
  214. called This is the number of times the function was called.
  215. If the function called itself recursively, the number
  216. only includes non-recursive calls, and is followed by
  217. a `+' and the number of recursive calls.
  218.  
  219. name The name of the current function. The index number is
  220. printed after it. If the function is a member of a
  221. cycle, the cycle number is printed between the
  222. function's name and the index number.
  223.  
  224.  
  225. For the function's parents, the fields have the following meanings:
  226.  
  227. self This is the amount of time that was propagated directly
  228. from the function into this parent.
  229.  
  230. children This is the amount of time that was propagated from
  231. the function's children into this parent.
  232.  
  233. called This is the number of times this parent called the
  234. function `/' the total number of times the function
  235. was called. Recursive calls to the function are not
  236. included in the number after the `/'.
  237.  
  238. name This is the name of the parent. The parent's index
  239. number is printed after it. If the parent is a
  240. member of a cycle, the cycle number is printed between
  241. the name and the index number.
  242.  
  243. If the parents of the function cannot be determined, the word
  244. `<spontaneous>' is printed in the `name' field, and all the other
  245. fields are blank.
  246.  
  247. For the function's children, the fields have the following meanings:
  248.  
  249. self This is the amount of time that was propagated directly
  250. from the child into the function.
  251.  
  252. children This is the amount of time that was propagated from the
  253. child's children to the function.
  254.  
  255. called This is the number of times the function called
  256. this child `/' the total number of times the child
  257. was called. Recursive calls by the child are not
  258. listed in the number after the `/'.
  259.  
  260. name This is the name of the child. The child's index
  261. number is printed after it. If the child is a
  262. member of a cycle, the cycle number is printed
  263. between the name and the index number.
  264.  
  265. If there are any cycles (circles) in the call graph, there is an
  266. entry for the cycle-as-a-whole. This entry shows who called the
  267. cycle (as parents) and the members of the cycle (as children.)
  268. The `+' recursive calls entry shows the number of function calls that
  269. were internal to the cycle, and the calls entry for each member shows,
  270. for that member, how many times it was called from other members of
  271. the cycle.
