Why does it go on limbo_die_list at all?
I noticed dwarf2out's gen_member_die() disallows generation of clones earlier,
by design:
/* Don't include clones in the member list. */
if (DECL_ABSTRACT_ORIGIN (member))
continue;
I played around trying to disable this "feature", but my approach ran into
various walls, and I decided instead to attack it from the front-end side. The attached
patch generates early DIEs for the C++ clones in the C++ parser. I'd be (un)happy to
revisit the dwarf2out approach if it's deemed more appropriate.
I'd still like to understand why disabling this doesn't work; I don't
like the special handling of clones in the front end.
