This is a very strange insn indeed:
(set (ge (reg:QI 0 AH [orig:26 w ] [26])
         (const_int 0 [0]))
     (plus:QI (plus:QI (ltu:QI (reg:CC 13 CC)
                 (const_int 0 [0]))
             (lt (reg:QI 0 AH [orig:30 a ] [30])
                 (const_int 0 [0])))
         (const_int 0 [0])))
