[Bug testsuite/46274] New: testsuite/gcc.dg: operator precedence

           Summary: testsuite/gcc.dg: operator precedence
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: ni...@nikai.net


The below tests appear not to work as intended because they
seem to always pass due to operator precedence (== and !=
before &, ^, |).
