Jules Villard 4cdb65c237 [pulse] |- is now true only of isomorphic graphs ... Summary: Previously we would say that `lhs <= rhs` (or `lhs |- rhs`) when a mapping existed between the abstract addresses of `lhs` and `rhs` such that `mapping(lhs)` was a supergraph of `rhs`. In particular, we had that `x |-> x' * x' |-> x'' |- x |-> x'`. This is not entirely great, in particular once we get pairs of state representing footprint + current state. I'm not sure I have an extremely compelling argument why though, except that it's not the usual way we do implication in SL, but there wasn't a compelling argument for the previous state of affairs either. This changes `|-` to be true only when `mapping(lhs) = rhs` (modulo only considering the addresses reachable from the stack variables).
