| In-thread program order. More... | |
| symbol_exprt | nondet_bool_symbol (const std::string &prefix) |
| void | read_from (symex_target_equationt &equation) |
For each read r from every address we collect the choice symbols S via register_read_from_choice_symbol (for potential read-write pairs) and add a constraint r.guard => \/S. More... | |
| symbol_exprt | register_read_from_choice_symbol (const event_it &r, const event_it &w, symex_target_equationt &equation) |
Introduce a new choice symbol s for the pair (r, w) add constraint s => (w.guard /\ r.lhs=w.lhs) add constraint s => before(w,r) [if w is from another thread]. More... | |
| Protected Member Functions inherited from partial_order_concurrencyt | |
| void | build_event_lists (symex_target_equationt &equation, message_handlert &message_handler) |
| First call add_init_writes then for each shared read/write (or spawn) populate: 1) the address_map (with a list of reads/writes for the address of each event) 2) the numbering map (with per-thread unique number of every event) More... | |
| void | add_init_writes (symex_target_equationt &) |
| For each shared read event and for each shared write event that appears after spawn or has false guard prepend a shared write SSA step with non-deterministic value. More... | |
| irep_idt | address (event_it event) const |
| Produce an address ID for an event. More... | |
| symbol_exprt | clock (event_it e, axiomt axiom) |
| Produce a clock symbol for some event. More... | |
| void | build_clock_type () |
| Initialize the clock_type so that it can be used to number events. More... | |
| void | add_constraint (symex_target_equationt &equation, const exprt &cond, const std::string &msg, const symex_targett::sourcet &source) const |
| Simplify and add a constraint to equation. More... | |
| exprt | before (event_it e1, event_it e2, unsigned axioms) |
Build the partial order constraint for two events: if e1 and e2 are in the same atomic section then constrain with equality between their clocks otherwise constrain with e1 clock being less than e2 clock. More... | |
