That's better, but now I get:

 XSTGInstrInfo.td:902:3: error: In RelAddr: XSTGRELADDR node requires
exactly 2 operands!

Which makes some sense as XSTGRELADDR is defined as:
def SDT_RELADDR       : SDTypeProfile<1, 2, [SDTCisInt<0>, SDTCisSameAs<0,
1>]>;
def XSTGRELADDR       : SDNode<"XSTGISD::RELADDR", SDT_RELADDR>;
