            Bug ID: 60782
           Summary: DWARF does not represent _Atomic
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tromey at gcc dot gnu.org

C11 has the _Atomic qualifier, but it isn't emitted
in DWARF.

I found this thread referencing the problem, but no
corresponding GCC bug report:

http://gcc.gnu.org/ml/gcc/2013-11/msg00139.html

The DWARF bug report is here:

http://www.dwarfstd.org/ShowIssue.php?issue=131112.1

This should be available in DWARF 5.
