摘　　要：目前随着多核处理器的蓬勃发展，软件尤其是编译器面临着巨大的机遇和挑战。链接后优化器作为一种优化辅助工具，可以在编译链接后对整个程序进行再优化，它克服了传统编译优化的局限，并且充分利用了链接后确定信息。本文参考Arizona大学为Alpha处理器设计的链接后优化器ALTO，提出了面向多核的链接后优化器整体设计框架，并重点分析了相关的几种链接后优化技术。As performance of the multicore processor increases, software, especially the compiler faces important chance and challenge. After Link Time Optimizer as a kind of optimization assistant tools can optimize the whole program after compilation. It overcomes the limitations of traditional compilers, and fully utilizes the information only available at link time. Guided by the ALTO developed by Arizona University for Compaq Alpha, we design the frame of an After Link Time Optimizer for multicore, and analyze the post link time optimization technique.
