I do think both examples are relevant. We don't really care whether it
is a "DWARF" or "ELF" symbol, since what we want is mapping a code
address to a name. We don't have to add extra dots in front of the
actual function names. We already have the real function name. IMHO you
are doing extra work to mangle a normal name into something that
resembles an artificial BFD symbol name. And that is what I think is
irrelevant in the elfutils case.
