No, but neither of those will even benefit a single cycle if you do them in
hand written assembler. They are too small and linear to offer any improved
speed. Any instruction scheduler of a reasonable compiler (which are the
compilers the POV-Team is using) will be better than a human optimizing the
same code. To the contrary, most compilers have global optimization
strategies that you effectively kill by adding bits and pieces of inline
assembler because most compilers won't for good reasons not touch (read:
optimize) user supplied hand written assembler code...
