--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
propagating insn 11 into insn 12, replacing:
(set (reg:QI 107 [ _3 ])
    (subreg:QI (reg:SI 108) 0))
failed to match this instruction:
(set (reg:QI 107 [ _3 ])
    (subreg:QI (eq:SI (reg:CC 66 cc)
            (const_int 0 [0])) 0))


Actually we could extend the cset patterns to do all integer modes.
