; TRACE stuff
; Allegro's trace facilities are somewhat limited. However it does have a
; function, advise, which is sufficiently general to allow it to imitate GCL's
; trace facilities as provided within ACL2. See Franz's documentation for
; information on advise and unadvise.
; We put over into old-trace the macro for trace that comes with Allegro.
; Thus one can type (old-trace foo) and get the effect that (trace
; foo) would have previously provided. We do not guarantee that using
; old-trace works well with trace$, however.

; The variables *trace-arglist* and *trace-values* will contain the
; cleaned up arglist and values of a traced function. The alist
; *trace-sublis* allows one to refer to these variables by more
; common names.

; What I am trying to do:
; Trace is called with a list of functions to be traced. Each element of
; this list can be;
; (Let foo be defined in common lisp but not in ACL2, and
; bar be defined within ACL2.)
; 1. the name of a non-acl2 function --- foo,
; 2. the name of an acl2 function --- bar,
; 3. a list whose only element is the name of a non-acl2 function --- (foo),
; 4. a list whose only element is the name of an acl2 function --- (bar),
; 5. a list whose car is the name of a non-acl2 function and whose
; cdr may contain the keywords :entry and :exit, each of which
; are followed by a function whose value will be printed upon
; entry and exit respectively of the function being traced ---
; (foo :entry (list (list 'arg-one (car si::arglist))
; (list 'arg-two (nth 1 si::arglist))))),
; 6. a list whose car is the name of an acl2 function and whose
; cdr may contain the keywords :entry and :exit, each of which
; are followed by a function whose value will be printed upon
; entry and exit respectively of the function being traced ---
; (bar :entry si::arglist
; :exit (if (eql (nth 1 si::arglist)
; (nth 0 values))
; 'FAILED
; (pretty-print-arg (nth 1 values))))
;
; In trace-pre-process we generate a new list as follows, where *1*bar denotes
; (*1*-symbol bar).
; 1. replacing foo with (foo foo),
; 2. replacing bar with (bar bar) & adding (*1*bar bar),
; 3, replacing (foo ...) with (foo foo ...)
; 4. replacing (bar ...) with (bar bar ...) & adding ((*1*bar ...) (bar ...)).
;
; In trace-process we generate suitable calls of advise and unadvise.
;
; Unless explicitly overridden by the :entry or :exit keywords,
; <entry trace-instructions> and <exit trace-instructions> print the
; arguments and returned values respectively. A minor amount of
; cleaning up is done, such as printing |*STATE*| instead of the
; entire state if it is one of the arguements or values.
