After the definition, no.  Could you try this instead?

let Constraints = "$dst = $addr", Uses= [GRP] in {
          def RelAddr : XSTGPseudo<(outs GPRC:$dst),
                     (ins GPRC:$spoff, GPRC:$addr),
                     "! RELADDR $spoff, $dst",
                     [(set GPRC:$dst, (XSTGRELADDR GPRC:$addr, 
GPRC:$spoff))]>;
}
