> Greetings, Jim. 
I don't trust the compiler explorer to accurately represent the full state of 
the situation, but, in any case, adding 3-4 instructions to a one instruction 
function could make things a lot slower. Can you please find existing 
benchmarks (or write new ones) to make sure that it isn't making the code 
slower?
