In general it shouldn't matter at all on any reasonably modern CPU (let's say less than 10 years old) unless you do it tens of thousands of times in a loop. Also gcc has reasonable default heuristics for this kind of stuff anyways (e.g. return NULL or return negative value is predicted unlikely by default) Cache misses are far more important to care about because they cost hundreds of cycles. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
