Abstract: A mechanism for evaluating a floating-point accuracy of a vehicle driving compatible compiler includes testing code compiled by a vehicle driving compatible compiler with code compiled by a testing environment compatible compiler, executing the vehicle driving compatible compiled code involves executing addition type floating points operations to provide a first floating point result, executing the testing environment compatible compiled code to perform addition type floating points operations to provide a second floating point result that corresponds to the first floating point result, comparing the first floating point result to the second floating point results to provide a comparison result, and determining the floating-point accuracy of vehicle driving compatible compiler based on the comparison result.
