Honored ContributorI still don't see why you have a problem....
Those gas macros convert assembly source lines into ones that gas itself understands. gas generates an object file containing the numeric instructions. The cpu logic is controlled by the instructions. This is what happens for any cpu. Altera encrypt the internals of the cpu so that it can't be copied, quite a lot of the operation can be inferred from the instruction set and instruction timings.
