I'd vote for -gdwarf-3 too.
E.g. your -feliminate-dwarf2-dups should be supported for -gdwarf-3 only
on 64bit arches, since otherwise you go against Dwarf-2 spec
(Dwarf-2 sais:
This type of reference (DW_FORM_ref_addr) is the size of an address on the
target architecture, while Dwarf-3 draft sais DW_FORM_ref_addr is 4/8 bytes
depending on whether it is 32 or 64bit dwarf format, similarly to
DW_FORM_strp).
