However, in a situation where it is a preindex load L converted before, it is possible that the input of one add is from the result of L and the input of another add is from the updated index of L. These two adds cannot be combined together clearly, so we need check to make sure two adds are from the same ResNo by adding code in the patch.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Unfortunately, I don’t have a test case for it.
