The structure MINI-PROFILER implements a minimalist profiler for
|
|
Scheme48 and scsh. Time is measuered using Scheme48's RUN-TIME
|
|
function from TIME.
|
|
|
|
Functions
|
|
=========
|
|
|
|
(profile-init!) -> unspecific
|
|
|
|
Initialize or reset the profiler. Calling this function will delete
|
|
all information collected during previous runs of the compiler.
|
|
|
|
(display-profile . port) -> unspecific
|
|
|
|
Print the profiling information acquired to PORT. If PORT is not
|
|
specified use CURRENT-OUTPUT-PORT.
|
|
|
|
Syntax
|
|
======
|
|
|
|
(account-for name body)
|
|
|
|
Evaluate BODY and stop the time needed for doing so. Account the
|
|
time needed for NAME. Especially useful for profiling code that
|
|
makes heavy use of high-order functions or lazy evaluation. Example:
|
|
|
|
(define (compile-funcall exp)
|
|
(account-for compile-funcall
|
|
(let ((op (compile (funcall-op exp)))
|
|
(arg (compile (funcall-arg exp))))
|
|
(lambda (env)
|
|
(account-for eval-funcall
|
|
(op (arg env stop-k)))))))
|
|
|
|
define-prof
|
|
|
|
DEFINE-PROF is a substitute for Scheme's DEFINE. Mini-profiler
|
|
accounts the time needed to evaluate the procedure bound with DEFINE
|
|
for DEFINE name.
