             Bug #: 55948
           Summary: __atomic_clear / __atomic_store_n ignore HLE_RELEASE
                    flags
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: andi-gcc@firstfloor.org


Passing __ATOMIC_HLE_RELEASE to __atomic_clear or __atomic_store_n does
nothing.
But it's valid to do a HLE release on a store.
