Functions
static void	throw_on_unsupported (const goto_programt &program)
	Throws an exception if a contract uses unsupported constructs like:
static void	generate_contract_constraints (symbol_tablet &symbol_table, goto_convertt &converter, exprt &instantiated_clause, const irep_idt &mode, const std::function< void(goto_programt &)> &is_fresh_update, goto_programt &program, const source_locationt &location)
	This function generates instructions for all contract constraint, i.e., assumptions and assertions based on requires and ensures clauses.
static const code_with_contract_typet &	get_contract (const irep_idt &function, const namespacet &ns)
