Mainline fails similarly. The failure results from this splitter
(define_split
[(set (match_operand:DI 0 "nonimmediate_operand" "")
(match_operand:DI 1 "input_operand" ""))]
"reload_completed && !TARGET_POWERPC64
&& gpr_or_gpr_p (operands[0], operands[1])"
[(pc)]
{ rs6000_split_multireg_move (operands[0], operands[1]); DONE; })
The "input_operand" predicate accepts any memory operand as the second operand.
rs6000_split_multireg_move thus needs to accept anything that we accept in
rs6000_legitimate_address. For this particular failure, that's a
(mem (symbol_ref (...))), which happens to satisfy legitimate_small_data_p.

It's probably the code under this comment:
/* We have now address involving an base register only.
If we use one of the registers to address memory,
we have change that register last. */
I expect the right thing to do is simply do
if (GET_CODE (breg) != SYMBOL_REF)
{
if (! REG_P (breg)) abort();
if (REGNO (breg) ...)
j = ...;
}
