摘要

程序通常使用相同的参数调用相同的函数，产生相同的结果。我们称这种现象为“功能重用”。前面，我们已经使用HP ATOM检测工具在一些SPEC2000整数基准测试中展示了这种行为。然而，这需要大量的手工分析，并对函数引起的副作用进行假设。在本文中，我们修改了一个著名的架构模拟器SimpleScalar，以分析多个基准测试来研究功能重用行为。

Performance enhancement by eliminating redundant function execution

Programs often call the same function with the same arguments, yielding the same results. We call this phenomenon, "function reuse". Previously, we have shown such a behavior for some of the SPEC2000 integer benchmarks using HP ATOM instrumentation tools. However, this required extensive analysis by hand, and assumptions regarding side-effects caused by functions. In this paper, we modified a well-known architecture simulator, SimpleScalar, to analyze multiple benchmarks to investigate the function reuse behavior.
