;;  (load "gprof.o")
;;  You must have a kcl image with profiling information and monstartup
;;  typically saved_kcp.   NOTE: if monstartup calls sbrk (true in
;;  most 4.3bsd's except sun >= OS 4.0)  you must be very careful to
;;  allocate all the space you will use prior to calling monstartup.
;;  If subsequent storage allocation causes the hole to move you will
;;  most certainly lose.  See below for instructions
;;  on how to construct saved_kcp.

;; If you want function invocation counts to be kept do
;; (setq compiler::*cc* (concatentate 'string compiler::*cc* " -pg "))
;; before compiling the relevant files.  (This is done when you load
;; lsp/gprof.o)

;; In the image saved_kcp Load in your files.  Load in gprof.o: (load
;; "lsp/gprof.o") Invoke monstartup once to setup buffers: (monstartup
;; lowpc highpc) eg. (monstartup #x800 3000000) [highpc should be a bit
;; bigger than the highest address you have seen when loading your files]
;; Use moncontrol to toggle profiling on and off: (moncontrol 0) to turn
;; profiling off, and (moncontrol 1) to turn it on.  Use
;; (wrtie-gmons+syms) to terminate with writing a gmon.out and syms.out
;; in the current directory.   I know of no way of clearing the buffers,
;; since secret routines set up the buffers, and we don't know where they
;; are or how large.  Thus all information is cumulative.

;; % gprof syms.out
;; will display the output (add -b) to make it briefer.

...  Interpretation: Foo is called 199 times by (parent) goo and once
by (parent) call_or_link (the setting up of the fast link).  Foo
itself calls (child) make_cons 200 of the 203 times that make_cons is
called...  Lower down we would see that goo is called twice.
