Abstract: A method of analyzing source code includes receiving, by a processor, an updated version of a computer program, the updated version including a source code. The method also includes preprocessing, by a compiler, the source code for a target computing platform. Preprocessing the source code by the compiler includes identifying a macro condition associated with one or more computer instructions enclosed by a macro, determining object code corresponding to the one or more computer instructions based on a current value of the macro condition, and generating object code and macro information for output to a debugger, the macro information including one or more breakpoint conditions in the macro.

Abstract: The present disclosure provides a load stabilization device, a control method thereof, and a computer readable storage medium. In the load stabilization device, a motion sensor, a processor, a stabilization motor, and a parallelogram mechanism constitute a closed-loop feedback control system. A control instruction for the stabilization motor is generated based on a velocity of a second end of the parallelogram mechanism in a direction of gravity relative to a ground, where the second end may carry a load, and the stabilization motor is controlled to drive, according to the control instruction, the parallelogram mechanism to rotate relative to a base, so as to at least partially offset or compensate for jitter of the load carried at the second end of the parallelogram mechanism in the direction of gravity, suppress disturbance generated at a first end of the parallelogram mechanism, and stabilize the load carried at the second end.
