cse1 generates:

;; Succ edge  EXIT [100.0%]  (fallthru)

;; Insn is not within a basic block
(insn 63 57 64 (set (reg:SI 100)
        (symbol_ref:SI ("__CTOR_END__") [flags 0x2]  <var_decl 0x7ffff0ced000
__CTOR_END__>)) -1
     (nil))

;; Insn is not within a basic block
(insn 64 63 65 (parallel [
            (set (reg:SI 99) 
                (plus:SI (reg:SI 100)
                    (const_int -4 [0xfffffffffffffffc])))
            (clobber (reg:CC 17 flags))
        ]) -1
     (nil))

;; Insn is not within a basic block
(insn 65 64 0 (set (reg:DI 98)
        (zero_extend:DI (reg:SI 99))) -1
     (nil))

This may lead to the DF problem.
