--- Comment #10 from Jason Merrill <jason at gcc dot gnu.org> 2013-01-31 19:32:35 UTC --- I don't think such an attribute belongs in the DWARF standard, since this is very much an internal detail of the ABI; another ABI might have just a single destructor with magic arguments, like the old G++ ABI. You need to know a lot about the destructor ABI as it is; looking for D0/D1 doesn't seem like a major additional burden to me.
