* iface/dve2/dve2.hh (load_dve2): Take a "dead" argument. * iface/dve2/dve2.cc (callback_context): Add a destructor to simplify... (dve2_succ_iterator::~dve2_succ_iterator) ... this one. (convert_aps): Skip the dead proposition. (dve2_kripke::dve2_kripke): Take a dead argument, and setup alive_prop and dead_prop. (compute_state_condition, get_succ): Use a cache for the conditions and successor of the last state, to share some work between these two function. Add loops on dead states. (load_dve2): Pass dead to dve2_kripke and convert_aps. * iface/dve2/dve2check.cc: Add a -dDEAD option. * iface/dve2/finite.test, iface/dve2/finite.dve: New file. * iface/dve2/Makefile.am: Declare them.

// The filename given can be either a *.dve source or a *.dve2C
|
|
// dynamic library compiled with "divine compile --ltsmin file".

// When the *.dve source is supplied, the *.dve2C will be updated

// The dead parameter is used to control the behavior of the model
|
|
// on dead states (i.e. the final states of finite sequences).
|
|
// If DEAD is "false", it means we are not
|
|
// interested in finite sequences of the system, and dead state
|
|
// will have no successor. If DEAD is
|
|
// "true", we want to check finite sequences as well as infinite
|
|
// sequences, but do not need to distinguish them. In that case
|
|
// dead state will have a loop labeled by true. If DEAD is any
|
|
// other string, this is the name a property that should be true
|
|
// when looping on a dead state, and false otherwise.
|
|
//
|

// This function returns 0 on error.
