I now believe that FORM_ref_addr should *always* point to a DIE, and
the intended encoding for location lists was class "constant". The
value is relocatable and relative to the beginning of the .debug_loc
section. Most likely, FORM_data4 (or data8) would be used for
location lists.

In order to clear up the (evident!) confusion surrounding the proper
encoding of loclists, etc., I propose to make the following changes
(all editorial, no substantive differences):

1. In the discussion of location lists (2.5.3 in Draft 1), add to the
end of the first paragraph, after the sentence, "A location list is
indicated by a location attribute whose value is represented as a
constant offset from the beginning of the .debug_loc section to the
first byte of the list for the object in question.":

    This offset is relocatable in a relocatable object file and
    relocated in an executable or shared object.

2. Similarly, in the discussion of DW_AT_stmt_list, (3.1, number 5),
add just before the last sentence of the second paragraph,

    This offset is relocatable in a relocatable object file and
    relocated in an executable or shared object.

3. Same section, number 6 (DW_AT_macro_info), second paragraph, add

    This offset is relocatable in a relocatable object file and
    relocated in an executable or shared object.

4. In section 7.5.4, Attribute Encodings, add the following paragraphs
after the existing paragraph describing class "constant":

    Constants are also used to represent offsets into the .debug_loc
    section. Any attribute that takes a DWARF expression as its
    value may have either a block or a constant form. The former
    indicates a single DWARF expression; the latter a location
    list (see Section 2.5.3). DW_AT_data_member_location is an
    exception; see Section 5.5.4.

    Attributes that reference .debug_line or .debug_macinfo also
    have a constant form.

5. In Figure 17, Attribute encodings, modify the "Classes" entry of
the following attributes as shown:

    DW_AT_data_member_location block, constant
    DW_AT_vtable_elem_location block, constant

Withdrawn by proposer in favor of 000410.3.
