Please use lowercase for type names.

I think this could be a function instead, that's usually preferred to
macros when possible.
Not sure about the name, maybe get_reg_offset().

Nitpick, I would just spell out "size", it's pretty short anyway.

This might be optimized, enabling each bit one by one doesn't seem
very efficient.

Nitpick, sizeof(*bytecode).
