Quoting "Paulo J. Matos" <paulo@matos-sorge.com>:

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])))

Smells like rtl sharing.
