check_contract()

void dfcc_swap_and_wrapt::check_contract ( const loop_contract_configt &  loop_contract_config, const irep_idt &  function_id, const irep_idt &  contract_id, std::set< irep_idt > &  function_pointer_contracts, bool  allow_recursive_calls  )

protected

Swaps-and-wraps the given function_id in a wrapper function that checks the given contract_id.

Generates globals statics:

static bool __contract_check_in_progress = false;
static bool __contract_checked_once = false;

Adds the following instructions in the wrapper function body:

IF __contract_check_in_progress GOTO replace;
ASSERT !__contract_checked_once "only a single top-level called allowed";
__contract_check_in_progress = true;
<contract_handler.add_contract_checking_instructions(...)>;
__contract_checked_once = true;
__contract_check_in_progress = false;
GOTO end;
replace:
// if allow_recursive_calls
<contract_handler.add_contract_replacement_instructions(...)>;
// if !allow_recursive_calls
ASSERT false, "no recursive calls";
ASSUME false;
end:
END_FUNCTION;
