采用更有效的方法分析x86架构下可执行文件的内存使用情况-Over the last seven years, we have developed static-analysis methods to recover a good approximation to the variables and dynamically allocated memory objects of a stripped executable, and to track the flow of values through them. It is relatively easy to track the effects of an instruction operand that refers to a global address (i.e., an access to a global variable) or that uses a stack-fr a me offset (i.e., an access to a local scalar variable via the fr a me pointer or stackpointer). In our work, our algorithms are able to provide useful information for close to 100　of such “direct” uses and defs.
