Issue 030603.1: Static data members
In the DWARF2 specification there was the following statement in section
5.5.4 "Structure Data Member Entries":
"If the member entry is defined in the structure or class
body, it has a DW_AT_data_member_location attribute
whose value is a location description that describes
the location of that member relative to the base address
of the structure, union, or class that most closely
encloses the corresponding member declaration."
However in the DWARF3 draft 8 specification this has been reworded in
section 5.6.6 "Data Member Entries" to read:
"For a data member of a structure, union or class, the
corresponding member entry has a DW_AT_data_member_location
attribute whose value describes the location of that
member relative to the base address of the structure
union, or class the most closely encloses the member
declaration."
If we consider static data members the original DWARF2 wording allowed for
the DW_AT_data_member_location attribute to be omitted (as the actual
location would be defined in the corresponding DW_TAG_variables
entry). However the DWARF3 wording implies that there should always be
a DW_AT_data_member_location attribute.
Is this new wording in the DWARF3 specification correct?
---------------------------
Others affirmed that Draft 8 seems wrong.
PROPOSAL:
Revert to the earlier sentence (change the sentence in 5.6.6
back to DWARF2 wording).
-------------------------------------------------------------
Accepted with following modification:
Replacing the new text with the old text isn't such a good idea,
but adding a "for a data member defined in a structure" addition
would be good.
