[Frama-c-discuss] differences between Store model and Typed model

The new memory model Typed of Frama-C/wp Oxygen is very interesting to improve efficiency of proof.

In the store model, it is clearly said that it is not able to process cast of pointeur type (in ?1.4 A consequence is that heterogeneous cast of pointers can not be translated in this model. For instance within this memory model, you can not cast a pointer to int into a pointer to char, and then access the internal representation of an int value in memory.).
I think, that for the same reason, we cannot handle memcpy.

And the Typed model is said to have quite the same expressivity than Store.
I'd like to have confirmation that Typed has the same limitation than Store for that point.

So, if it is the case, only Runtime model is able to process memcpy ?

Thanks in advance,
