Agreed. I suppose it's slightly more self-documenting than NOTE_INSN_DELETED, and it's good to be consistent with other ports. David, FWIW, a patch to add those two lines is pre-approved. If you've already tested the NOTE_INSN_DELETED version, don't feel you need to test the whole thing again with the other note; as long as cc1 compiles, that's fine.
