[Bug nptl/14350] New: Clarify acquire/release semantics for atomic_exchange_and_add


http://sourceware.org/bugzilla/show_bug.cgi?id=14350

             Bug #: 14350
           Summary: Clarify acquire/release semantics for
                    atomic_exchange_and_add
           Product: glibc
           Version: 2.17
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: nptl
        AssignedTo: unassigned@sourceware.org
        ReportedBy: maxim.kuvyrkov@gmail.com
                CC: drepper.fsp@gmail.com
    Classification: Unclassified


Most uses of atomic_exchange_and_add currently imply both acquire and release
semantics and that can be improved by using more specific
atomic_exchange_and_add_acq and atomic_exchange_and_rel.
