           Summary: GCC doesn't generate
                    DW_TAG_imported_{module,declaration} entries
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: carlton@bactrian.org
                CC: gcc-bugs@gcc.gnu.org

GCC doesn't generate DW_TAG_imported_{module,declaration} entries when
compiling C++ files with using directives, using declarations, and namespace
aliases.  This isn't as important as the fact that it doesn't generate
DW_TAG_namespace entries, but it's still sub-optimal.

Verified by compiling programs with GCC 3.2.3 and by getting the current
mainline sources from CVS and examining dwarf2out.c for "DW_TAG_imported".
