 		 #140915 - need recursive calls? use a chip that can take it
Responding to: ???'s previous message
Ryan: I hope you don't mind me answering some of these.

Russ Cooper said:
With OCG, are recursive calls still a problem on machines that don't have a hardware stack?


It's just not worth implementing a solution to support recursion on chip's that don't have a stack you can manipulate. Recursion is not used that often anyway in (small) embedded apps, and it your design really calls for it, then choose a chip that can handle it. (ie, not a PIC)

In the case of our (soon to be released) OCG based 8051 compiler, we've implemented a hybrid solution. Both conventional and compiled (statically allocated) stack are allowed and the code generator chooses the appropriate/most efficient method automatically.

What\'s more important optimisations or debugging?            01/01/70 00:00      
   as Ive said before,you have two versions            01/01/70 00:00      
      Fly what you debug; Debug what you fly            01/01/70 00:00      
         Yes and No            01/01/70 00:00      
            and no...            01/01/70 00:00
