 		 #143123 - SDCC function startup code
Responding to: ???'s previous message
In the DS390 version of SDCC there is a --stack-probe switch (it is very easy to implement it for other targets - in fact I wonder why it is not so) - which causes a call to a function with particular name, with the intention to perform a stack overflow check. Of course this means extra 2 bytes on the stack and certain slowdown - nothing is free.

SDCC, being open source, offers also an other opportunity, although at an expense of non-trivial programming effort: it could be possible to perform an exact stack counting.

                     Michal, you are cheating! :-)            01/01/70 00:00      
                        This was the reason :)            01/01/70 00:00      
                     ... but it's easy to do it in C :-)            01/01/70 00:00      
                        I dont trust to any any any compiler :)            01/01/70 00:00      
            Stack overflow?            01/01/70 00:00      
               I think this will be complicated            01/01/70 00:00      
                  1 of 2 ways            01/01/70 00:00      
                     Thx            01/01/70 00:00      
         The Compiler does not protect you            01/01/70 00:00      
            Like SDCC...            01/01/70 00:00      
               Better?            01/01/70 00:00
