Hi, My pass heavily relies on llvm::Loop's getSmallConstantTripCount method. However, I found that it doesn't work for some simple cases. In the following example, I can get the constant trip count of the outermost loop if statement "a[l] = a[l] + 1" is there. After commenting out this line, the returned constant trip count for that loop is 0. In my pass, I traverse the nested
