I do see your point and I found it interesting (I've had to optimize filters in the past and used the same process of coding C and looking at the assembly), but how can "beating the compiler" be interpreted as anything but writing better code than the compiler?

Writing optimized code generally involves looking at larger sections of the problem / code base and picking a different approach based on global conditions. So, when you and the compiler are booth looking at the same code base, but you find a better local approach based on a global condition you have beaten the compiler. Even if all you did was tell it about that condition.
