Fix previous commit: poison only class members, simpler tests Summary: Poisoning applied to only class members, and before dtors for base class invoked Implement poisoning of only class members in dtor, as opposed to also poisoning fields inherited from base classes. Members are poisoned only once, by the last dtor for a class. Skip poisoning if class has no fields. Verify emitted code for derived class with virtual destructor sanitizes its members only once. Removed patch file containing extraneous changes. Reviewers: eugenis, kcc Differential Revision: http://reviews.llvm.org/D11951 Simplified test cases for use-after-dtor Summary: Simplified test cases to focus on one feature at time. Tests updated to align with new emission order for sanitizing callback. Reviewers: eugenis, kcc Differential Revision: http://reviews.llvm.org/D12003 llvm-svn: 244933

Implementation and testing for poisoning vtable ptr in dtor. Summary: After destruction, invocation of virtual functions prevented by poisoning vtable pointer. Reviewers: eugenis, kcc Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D12712 Fixed testing callback emission order to account for vptr. Poison vtable in either complete or base dtor, depending on if virtual bases exist. If virtual bases exist, poison in complete dtor. Otherwise, poison in base.
