This revision is now accepted and ready to land.
Looks good to me, other than some super tiny nits! Thanks for iterating on this
-- it is awesome that the analyzer will be able to model this now!!
================
Comment at: include/clang/StaticAnalyzer/Core/PathSensitive/SVals.h:463
+class PointerToMember : public NonLoc {
+ friend class ento::SValBuilder;
----------------
I think this deserves a comment about why it is a NonLoc and why it needs to
keep the PointerToMemberData with the list of CXXBaseSpecifiers.
================
Comment at: lib/StaticAnalyzer/Core/ExprEngineC.cpp:269
+ StmtNodeBuilder &Bldr, ExplodedNode* Pred) {
+ // Recover some path-sensitivty by conjuring a new value.
+ QualType resultType = CastE->getType();
----------------
While we're here we might as well correct the misspelling --> "path
sensitivity".
================
Comment at: test/Analysis/pointer-to-member.cpp:74
- // FIXME: Should emit a null dereference.
- return obj.*member; // no-warning
+ return obj.*member; // expected-warning{{}}
+}
----------------
Can you include the warning text in the expected-warning directive? This will
ensure we keep emitting the correct warning in the future.
