I think return note1 == note2; will simplify your codes and fix this issue.
NOTEs are not shared (look at how they get chained and it's obvious
they're not shared). So you can't use pointer equality, you must use
rtx_equal_p.
More generally, nodes are not shared unless explicitly documented as
such in the internals manual, "Sharing" section.
