xazax.hun added inline comments.

Comment at: clang/lib/StaticAnalyzer/Checkers/SmartPtrModeling.cpp:139
+
+ const auto *MethodDecl = dyn_cast_or_null<CXXMethodDecl>(OC->getDecl());
+
----------------
You should never get null here due to `isStdSmartPointerClass` guarding above.
I think the null check could be transformed into an assert.
================
Comment at: clang/lib/StaticAnalyzer/Checkers/SmartPtrModeling.cpp:141
+
+ if (!MethodDecl || !MethodDecl->isOverloadedOperator())
+ return;
----------------
You have a `CXXMemberOperatorCall` which already represents an overloaded
operator. This check is either redundant or could be an assert instead.
================
Comment at: clang/lib/StaticAnalyzer/Checkers/SmartPtrModeling.cpp:144
+
+ OverloadedOperatorKind OOK = MethodDecl->getOverloadedOperator();
+ if (OOK == OO_Star || OOK == OO_Arrow) {
----------------
In case `CXXMemberOperatorCall ` class does not have a way to query the
overloaded operator kind maybe it would be worth to add a helper method to that
class. So you can do most of the checking using one interface only.
================
Comment at: clang/lib/StaticAnalyzer/Checkers/SmartPtrModeling.cpp:198
+ *InnerPointVal);
+ C.addTransition(State);
+ }
----------------
It is possible that both `updateTrackedRegion` and this adds a transition. Both
transition will have the same predecessor, i.e. you introduce a split in the
exploded graph. Is this intended?
