+      for (Value *PtrOperand : getPointerOperands(*TopVal, *DL, TTI)) {

It stops tracking through instructions generating pointers with assumed AS. It's not necessary to check their operands as the result is assumed. For instructions without assumed AS results, we need to track them through their operands.
