Abstract

The invention discloses an exception processing method and an exception processing device. The method comprises the following steps of: detecting one or more exception states in instructions; searching attribute information corresponding to the exception states in an instruction exception state list, wherein the instruction exception state list saves the attribute information of various exception states; and displaying the attribute information corresponding to the exception state. The method and the device can quickly and accurately position exception places, improve the accuracy and processing efficiency for processing exception, facilitate software code maintenance, and improve accessibility of users and robustness of software.

Description

technical field [0001] The invention relates to a method and device for abnormal processing. Background technique [0002] The computer's exception-handling capabilities provide the means to handle any unexpected or unusual conditions that arise while a program is running. Exception handling uses the try, catch, and finally keywords to attempt potentially unsuccessful operations, handle failures, and clean up resources afterward. Treating exceptions usually does not simply end the program, but instead executes a special piece of code to handle the exception and tries to resume the program to continue execution. When an exception occurs, the system starts from the code that generates the object, traces back layer by layer along the call stack of the method, finds the corresponding processing code, and hands the exception object to the method for processing. [0003] There are two basic models of exception handling theory: one is called "termination model", in this model, th...
