Re: how to optimize a for loop

I have this loop (all variables are pointers):
for (foo = bar; foo > baz; foo--)
*(foo+1) = *foo;
How do I optimize the pointer swap so that it uses -- and ++ or unary
+- instead of +1 (if possible - I don't want to have more #defines
than code)?
IOCCC winners can really help me with this :P

What makes you think that replacing "+1" with "++" is an optimization?
