ill never trust the compiler. everyone always told me. trust the compiler!! i believed them!! i was young. inexperienced. until one day. 2014. i realised u can do zero-overhead while loops on a atmel. or maybe it was a pic. cant remember. anyway the compiler doesnt do it, you have to do it yourself!!! you have to type asm() in. with your hands. it doesnt do it for you!!!! and at that point im like, jeez, why am i even using a compiler. good for nuthin piece of garbage
