Metering LISP code

[doug@clarity.Princeton.EDU (Douglas Merrill)]

Hi to all...  Tried to post this yesterday, but it didn't work.  So,
one more time...

Does anyone out there have some code to do code metering in MACL2.0?
I have some code that supposedly runs under 1.3.2, but doesn't under
2.0.  I didn't even understand the *error message*, much less have a
good idea about how to fix it!

Basically, I've got a big system that was written in bits an pieces
over a long period of time; some of the code is really inefficient, so
I've started optimizing.  I spent a week or so doing what I thought
was the greatest optimization ever -- but it didn't speed the system
up at all.  Oh!  This function only got called once in the whole time.
No wonder it isn't faster.

So, I want a tool to profile this mass of code to help me figure out
what to optimize next.  Help would be greatly appreciated.
