resultt
Result of running the decision procedure.
There are a large number of kinds of tree structured or tree-like data in CPROVER.
const irep_idt & id() const
Class that provides messages with a built-in verbosity 'level'.
std::size_t number_of_solver_calls
void write_footer()
Writes the end of the SMT file to the smt_convt::out stream.
static std::string convert_identifier(const irep_idt &identifier)
std::unordered_map< irep_idt, bool > set_values
The values which boolean identifiers have been smt2_convt::set_to or in other words those which are a...

std::vector< bool > boolean_assignment
identifier_mapt identifier_map
std::size_t no_boolean_variables
message_handlert & message_handler
std::string decision_procedure_text() const override
Return a textual description of the decision procedure.
resultt dec_solve() override
Run the decision procedure to solve the problem.
resultt read_result(std::istream &in)
std::stringstream cached_output
Everything except the footer is cached, so that output files can be rewritten with varying footers.

#define UNREACHABLE
This should be used to mark dead code.
std::string to_string(const string_not_contains_constraintt &expr)
Used for debug printing.
