sgatev added inline comments.
================
Comment at:
clang/include/clang/Analysis/FlowSensitive/DataflowAnalysisContext.h:156
+ TopBoolValue &createTopBoolValue() {
+ return takeOwnership(std::make_unique<TopBoolValue>());
----------------
Please add a comment.
================
Comment at: clang/include/clang/Analysis/FlowSensitive/DataflowEnvironment.h:291
+ BoolValue &makeTopBoolValue() const {
+ return DACtx->createTopBoolValue();
----------------
Please add a comment.
================
Comment at: clang/include/clang/Analysis/FlowSensitive/Value.h:100
+public:
+ explicit TopBoolValue() : BoolValue(Kind::TopBool) {}
+
----------------
`explicit` seems unnecessary.
================
Comment at: clang/lib/Analysis/FlowSensitive/WatchedLiteralsSolver.cpp:237-238
+ case Value::Kind::TopBool:
+ // Nothing more to do. Each `TopBool` instance is mapped to a fresh
+ // variable.
+ break;
----------------
Where? Does that mean that `TopBool` never reaches the solver? I think it'd be
good to clarify.
================
Comment at:
clang/unittests/Analysis/FlowSensitive/TypeErasedDataflowAnalysisTest.cpp:1220
+ (void)0;
+ /*[[p2]]*/
+ }
----------------
Why do we need to check two code points here and in the test below? It's not
obvious what the difference between `p1` and `p2` is.
