Could that be construed to say:

        "we should support doing it either way, depending on what CPU
        is being tuned for?"

because if you're going to violate peoples' expectations to implement
an optimization for a specific processor (which ultimately makes the
assembler implementation more complex), then shouldn't you afford that
opportunity for other processors?


No, I don't have a performance bias for either 'add' or 'or' for my
parts.  However, I do have a strong bias against code the implements
things in violation of peoples expectations, and, most especially code
that tells you that two things are the same, when they're not (e.g.,
disassembler).
