I don't see this "r" in any of our sources. Moreover, even binutils have a
switch to stop printing it.

Actually for binutils things are simpler: they have most parts of what I had to
create here. For example, they already have a comfortable way to find the
instruction operands. And, unlike with our code, this is grouped in one place
-- libopcode.
