Jules Villard 4c357e434b [pulse] apply discovered variable equalities eagerly ... Summary: This resolves a few instances of false negatives; typically: ``` if (x == y) { // HERE *x = 10; *y = 44; // THERE } ``` We used to get ``` HERE: &x->v * &y ->v' * v == v' THERE: &x->v * &y ->v' * v == v' * v |-> 10 * v' |-> 44 ``` The state at THERE was thus inconsistent and detected as such (v` and `v'` are allocated separately in the heap hence cannot be equal). Now we normalize the state more eagerly and so we get: ``` HERE: &x->v * &y->v THERE: &x->v * &y->v * v |-> 44 ``` Reviewed By: skcho Differential Revision: D26488377 fbshipit-source-id: 568e685f0		4 years ago
