   if (S.checkingForUndefinedBehavior()) {
     SmallString<32> Trunc;
     APResult.trunc(Result.bitWidth()).toString(Trunc, 10);
     auto Loc = E->getExprLoc();
-    S.report(Loc, diag::warn_integer_constant_overflow) << Trunc << Type;
+    S.report(Loc, diag::warn_integer_constant_overflow)
+        << Trunc << Type << E->getSourceRange();
