;; For all symbolic operands *except* function addresses and read-only
;; operands (which live in TEXT space and do not require relocation).

;; The constraints are a little strange.
;; The basic idea is to prefer %r1 as much as possible for register
;; allocation (hence we do not allow regclass to know about the general
;; register case (via *r).
;; We also want to avoid spilling %r1 as that will cause every use
;; of %r1 to be reloaded, so we make the %r1 case very expensive
;; as far as reload is concerned (via !a).
;;
;; The real solution is to not spill all pseudos allocated to %r1
;; when %r1 is needed as a spill register, but that is considerably
;; more difficult than coercing decent behavior via constraints.
