Sam Blackshear 3a7d50e15b [thread-safety] more precise ownership domain Summary: We previously lumped ownership predicates in with all other predicates. That limited us to a flat ownership domain. This diff separates out the ownership predicates so we can have a richer lattice of predicates with each access path. This lets us be more precise; for example, we can now show that ``` needToOwnBothParams(Obj o1, Obj o2) { Obj alias; if (*) { alias = o1; } else { alias = o2; } alias.f = ... // both o1 and o2 need to be owned for this to be safe } void ownBothParamsOk() { needToOwnBothParams(new Obj(), new Obj()); // ok, would have complained before } ``` is safe.
