            Bug ID: 42036
           Summary: RuntimeDyldMachOARM.h - comparison is always true due
                    to limited range of data type
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Generic Execution Engine Support

      uint16_t LowInsn = readBytesUnaligned(LocalAddress + 2, 2);
      assert((LowInsn & 0xf800) != 0xf8000 &&
             "Unrecognized thumb branch encoding (BR22 low bits)");

This warning suggests a typo in the assertion - should it be:

      assert((LowInsn & 0xf800) != 0xf800 &&
             "Unrecognized thumb branch encoding (BR22 low bits)");
