           Summary: Another InstCombine issue
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Scalar Optimizations
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: asl at math.spbu.ru

Consider the attached bytecode. This is just -O0 compiled bytecode from gcc

Running "opt -instcombine" will lead to "eq" comparison turn to "slt", which is
definitely wrong.
