gnupic: Thread: A few questions about new version of mary

Hi Francisco,

I have one more question regarding the new version of mary.
Does the return stack use only the hardware stack (and the call depth
is limited to 8 (or even 7 when using interrupts))?
Do you use any call optimizations with storing of return address in RAM
for non-recursive calls?
Does the new banking scheme cover the CODE memory banking too?
Is any "snapshot" of the new version available?

				TIA & Greetings

Before buying any hardware ask the dealer if it is Open Source friendly!!!

Hello.

Yes, because mary compiles to native code, and it's not easy to have a 
software return stack in that mode.

If you call a word and then return, it translates to a jump. 

> Does the new banking scheme cover the CODE memory banking too?

More than 2k code is supported.

Currently no, but I am considering writing a short warning and wrapping 
what I have right now. So, nobody will have to wait too much. In fact, 
currently there is only one important bug in the code. Besides the full 
documentation for the new processor definition file is lacking.

Thanks for your interest.

Regards.
