Abstract: IA-64 architecture support predication, which offers more opportunities for exploiting instruction level parallelism. It turns out, however, that compiler optimizations to take advantage of such architectural features can profoundly restructure the program’s code, making it potentially difficult to reconstruct the original program logic from an optimized Itanium executable. This paper describes several techniques to undo some of the effects of such optimizations and thereby improve the quality of reverse engineering such executables.

摘要： IA-64体系结构支持判断执行，提高指令级并行性，但是编译器为了充分利用该特性而做的优化将程序代码进行深度重构，对逆向工程来说很难从优化后的可执行代码中恢复原程序逻辑。该文提出了消除谓词的反优化技术，提高了可执行代码逆向工程的质量。
