I've just converted from using the memory stack to use Itanium's
register stack engine, to do exactly that. The only issue remaining is
for local variables in previous scopes .. while in memory I just move
down the activation frames, RSE simply "hides" the previous frames. I
know Itanium supports rotating registers (so I assume somehow I can
access previous register stack frames), but haven't figured out a
uniform way of doing it. I'd love to know how it's tackled.

Thanks for your support!
K.Phillips.
