how function calls are treated: a) there is an edge from each call site to the function head b) there is an edge from the last instruction (END_FUNCTION) of the function to the instruction following the call site (this also needs to set the LHS, if applicable)
"this" is the domain before the instruction "from" "from" is the instruction to be interpreted "to" is the next instruction (for GOTO, FUNCTION_CALL, END_FUNCTION)
PRECONDITION(from.is_dereferenceable(), "Must not be _::end()") PRECONDITION(to.is_dereferenceable(), "Must not be _::end()") PRECONDITION(are_comparable(from,to) || (from->is_function_call() || from->is_end_function())
Implements ai_domain_baset.
