[Manas Gupta via Phabricator via cfe-commits]

manas added inline comments.


================
Comment at: clang/lib/StaticAnalyzer/Core/RangeConstraintManager.cpp:1485
+  if (ResultType.isUnsigned() ||
+      ((LHS.From() >= 0 && RHS.From() < 0) &&
+       (LHS.To() >= 0 && RHS.To() < 0)) ||
----------------
@vsavchenko one thing crossed my mind is that, shouldn't I compare `From` and `To` values with  `llvm::APSInt Zero = ValueFactory.getAPSIntType(T).getZeroValue()` instead of literal `0`?
