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)
in some cases, function calls are skipped, in which case: c) there is an edge from the call instruction to the instruction after
"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())
The history aware version is used by the abstract interpreter for backwards compatability it calls the older signature
