--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Broken by r235913, before that it was starting with that copy_rtx.  I think we
should just restore it back.
The  if (repl || reg2) before add_reg_note also doesn't make sense to me,
because if that is false, then if (!repl && !reg2) is true and we wouldn't be
using different path (and nothing changes repl or reg2).
