Abstract

The invention discloses a method, a system and a device for analyzing and modifying a multi-level assembly code snippet. The method comprises the following steps of: acquiring an assembly file and reading an assembly code according to the assembly file; converting the assembly codes into intermediate format representation and connecting in sequence to obtain a linear linked list; and analyzing the linear linked list to obtain code information of different levels. The system comprises a reading module, a connection module and an analysis module. The device comprises a memory and a processor used for executing the multi-level assembly code snippet analysis and modification method. By using the method and the device, information of different levels of the assembly codes can be analyzed, and the assembly codes of the corresponding levels can be replaced according to user requirements. The multi-level assembly code snippet analyzing and modifying method, system and device can be widely applied to the technical field of computer information processing.

Description

technical field [0001] The invention relates to the technical field of computer information processing, in particular to a method, system and device for analyzing multi-level assembly code fragments. Background technique [0002] Because the assembly code loses the original abstract semantics of the high-level language during the compilation process, the logical relationship of the code is difficult to understand. Developers need to handle the storage allocation and input and output of each instruction and each data, and also need to clarify the program running process. The working status of each step in the process, so manually modifying the assembly code is a huge cost for the developer. At the same time, the code volume of the assembly code is generally large, and the manual modification of the developer is more error-prone. At the same time, the method of inline assembly is only applicable to The replacement of some small code fragments and the extensive use of inline as...
