>
> The current literal replacement framework contains basic scalar literal
> replacement as well as the replacement of small matrix operations with their
> literal results. If this framework is invoked with temporary matrix objects
> created during size propagation any matrix operation would obviously fail. So
> far, this created no problems because literal replacement was tied to
> recompilations that are not in-place, i.e., recompilations that create a deep
> copy of the hop dag, which in turn only happens for single-dag recompilations.
> This task aims to decouple the literal replacement from in-place
> recompilations in order to increase the literal replacement potential and
> allow for a more flexible use of this literal replacement framework.
