[PATCH] D74541: [Analyzer] Use note tags to track iterator increments and decrements

[Artem Dergachev via Phabricator via cfe-commits]

NoQ added inline comments.


================
Comment at: clang/lib/StaticAnalyzer/Checkers/IteratorModeling.cpp:489-490
+    StringRef ChangeText =
+      ((Op == OO_Plus || Op == OO_PlusEqual) != (ChangeVal <= 0)) ?
+      "incremented" : "decremented";
+    const NoteTag *ChangeTag = getChangeTag(C, ChangeText, ItE,
----------------
Can we assert out the `ChangeVal == 0` case or make a better message for it (`"unchanged"` or something like that)?
