基于数据流分析的寄存器参数恢复方法

摘要

Aiming at the register parameter recovery problem in the process of de, compiling the executable programs on the IA32 architectures and based on Application Binary Intefface(ABI) conventions for IA32, this paper analyzes the characteristics of register parameters, and uses register definition and usage information to propose a method for register parameter recognition and recovery information of registers, which is gained by reaching definition analysis and ud-chain.%针对在反编译IA32体系结构可执行程序过程中涉及的寄存器参数恢复问题,基于IA32适用的ABI约定,分析寄存器参数的特征,借鉴数据流分析中到达-定义分析及使用-定义链等经典方法,利用寄存器定义和使用等信息,提出一种寄存器参数的识别、处理及实参恢复的方法.
