--- Comment #8 from Alan Modra <amodra at gmail dot com> ---
What you'd need is some way for the linker to recognise that references from
vtables should not be followed for the purpose of marking sections against
garbage collection, and some way of marking the functions called at their call
sites.  The former is easy enough, the latter is impossible.  The linker can't
know the function called, by the very nature of virtual functions.
