Hmm.. Using bytes does not help the register pressure and in fact slightly increases code size. If the byte register instructions on x86 were more symmetric this might be different, but...
sad that they don't work well.
I cannot think of an architecture where using bytes would be better. The increase in code size is because of the need to clamp the values at their maximum so code like this fails properly.
They exist :-)
thanks for the tip, this is very good to know.
thanks
