--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This code will not work with anything more fancy than insns, it does not
support code_labels.

```
              for (rtx_insn *curr =3D after_rtl_seq;
                   curr !=3D NULL_RTX;
                   curr =3D NEXT_INSN (curr))
                emit_insn (copy_insn (PATTERN (curr)));
              rtx_insn *copy =3D get_insns ();
              end_sequence ();

```=
