Well, I guess you need to do two things:
- Define the PREDICATE_CODES macro -- if this is undefined,
genrecog will consider *any* target-defined predicate as
potentially allowing non-lvalues, because it cannot know
better.
- Actually define two distinct predicates, one that allows
non-lvalue and one that doesn't, and use them as appropriate.

Well, you could also simply ignore the warning -- nothing
is going to go wrong because of it.
