  dwarf_add_AT_dataref(Dwarf_P_Debug
    dbg, Dwarf_P_Die die, Dwarf_Half
    attr, Dwarf_Unsigned pc_value,
    Dwarf_Unsigned sym_index, Dwarf_Error
    *err);
dwarf_add_AT_dataref() creates an attribute
  descriptor for a relocatable address and attaches it to the debugging
  information entry referenced by argument die.
If flag DW_DLC_SIZE_64 is set, the address
    value will be 8 bytes in size and of the DWARF form
    DW_FORM_data8. Otherwise, the address value will be
    4 bytes in size and of the DWARF form
  DW_FORM_data4.
Argument dbg should reference a DWARF producer instance allocated using dwarf_producer_init(3) or dwarf_producer_init_b(3).
Argument die should reference a debugging information entry allocated using dwarf_new_die(3).
Argument attr specifies the attribute code of the created attribute descriptor.
Argument pc_value specifies the value of the relocatable address.
Argument sym_index specifies the ELF symbol index of the symbol to be used for relocation.
If argument err is not NULL, it will be used to store error information in case of an error.
dwarf_add_AT_dataref() returns the
  created attribute descriptor. In case of an error, function
  dwarf_add_AT_dataref() returns
  DW_DLV_BADADDR and sets the argument
  err.
dwarf_add_AT_dataref() can fail with:
