Right but it’s the address that’s invariant not the store so hasLoopInvariantStore is a misleading name. How about hasStoreToLoopInvariantAddress?

No, not hasLoopInvariantStore but hasAccessToLoopInvariantAddress.
You will also need to generate the memchecks for such accesses in canCheckPtrAtRT and addRuntimeCheck. Without those memchecks passing, the result of the dependence analysis is incorrect.
