Detailed Description

Main class orchestrating the the whole program transformation for function contracts with Dynamic Frame Condition Checking (DFCC)

All functions of the model are extended with a ghost parameter representing a dynamic frame and all their assignments are instrumented and checked against the dynamic frame parameter.

Targets specified by assigns clauses and frees clauses of the contracts are reified into dynamic data structures built by ghost code embedded in the program and are propagated through function calls and function pointer calls as ghost call arguments.
