not xor is aka xnor. You probably want this without the two "not"
operations.

Thanks, that worked. I ended up using:
(define_insn "cmpcc_xor"
[(set (match_operand:CC 0 "register_operand" "=C")
(compare:CC
(not:SI (xor:SI (match_operand:SI 1 "register_operand" "%r")
(match_operand:SI 2 "register_operand" "b")))
(const_int

When a compare is in a parallel, the compare must be the first
operation. You have it second. This kind of pattern should work. You
can find many examples of it in the sparc.md
