Grargh! When I wrote our coding guidelines at work, I
made it very
clear that comments shuold describe the algorithm, not just each line of
code. So, for example, instead of "Push R2 onto the stack" it would say
"squirrel R2 away because it's gonna get clobbered in a minute and we'll
need it again", followed later by "retrieve the value we saved earlier,
so that now we can ...".
...or "I'm saving all of the registers by habit because I've been burned
too many times when I forgot to save one. Besides, what's a few wasted
cycles between friends?"
Anyone recognize the system for which the above assembly code is written?
Cheers,
