Also, using a string like that rather than some kind of

By "some kind of identifier" do you just mean replacing "code,alternative"
with a string that doesn't have a comma?
Yeah. It really looks too much like the definition of attribute values IMO.
The problem with define_icode_attr is that you get combinatorial
explosion with the type of the return value. At the moment we just have
integers and enums (which can be defined by define_enum_attr as well as
define_attr), but who knows what we'll have in future? :-)
Maybe
(define_typed_attr {enum,int} {insn,icode,icodealt}
[all the usual stuff])
