One way to address this is to generate the union of the DIEs into a partial
unit.    [ This does create the problem of having references from that unio=
n to
DIEs that are unique to a certain CU, and consequently don't have a duplica=
te
chain. ]

Another way is to factor out the common part of the DIEs into a partial uni=
t,
and include it from the original DIEs using DW_AT_specification.
