Make sure you do a good literature search before you try to
publish anything.  A lot of work has been done in this area.
If I recall what I have read, without doing anything tricky
the optimal number of frames to save/restore is 1.  Of course,
if you are doing something tricky, or if it is real expesive
to load the code to save/restore regs on whatever architecture
you are exploring, then your mileage will vary.  Unfortunately,
I do not have the reference handy, but if I find it, I'll post
it.  Oh, and if your interested in procedure-intensive
benchmarks, try Towers of Hanoi.  Not a very realistic benchmark,
but there you go.
