    Dwarf_Error *err);
dwarf_add_AT_location_expr() creates an
  attribute descriptor for a location expression and attaches it to the
  debugging information entry referenced by argument die.
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 loc_expr should reference a location expression descriptor allocated using dwarf_new_expr(3).
The attribute created by function
    dwarf_add_AT_location_expr() will have one of the
    DWARF forms DW_FORM_block,
    DW_FORM_block1,
    DW_FORM_block2 or
    DW_FORM_block4, depending on the size of the byte
    stream generated by the location expression descriptor referenced by
    argument loc_expr.
If argument err is not NULL, it will be used by to store error information in case of an error.
dwarf_add_AT_location_expr()
  returns the created attribute descriptor. In case of an error, function
  dwarf_add_AT_location_expr() returns
  DW_DLV_BADADDR and sets the argument
  err.
dwarf_add_AT_location_expr() can fail with:
