Thanks Chris. I was actually asking about analyzing Core output in general.
I'm well aware of the problems we're having with the nbody entry.

I'm convinced my list based version can go faster than it is now. That's why
I was asking if Don could put together a few notes on how to optimize inner
loops using -ddump-simpl and the resulting Core code.

So, I guess my request is along the same lines as your earlier one:

I would love to have a tutorial about common situations one comes across
when looking at the Core output.
