v0.1.1: 感谢小神师兄的提醒与指导!


CS: APP 第五章从编译器与处理器的角度,利用c语言实现,描述了程序通用的优化方法。这种通用的方法的度量因不同处理器而异,但策略是相似的。除开算法上的优化,基于机器的系数级优化是本章的重点。我们利用CPE(Cycle Per Element)来度量程序的执行效率,以4代 core i7-47x0 以及 GCC4.8.x 为样例机器,通过多种方式来对程序进行系数级优化。

CS: APP chapter 3 notes: (variable) stack frame

Introduction

Chapter III of CS: APP mainly describes x86_64 assembly in details, which gives a dictionary-like introduction. Nevertheless, the reason why performming this chapter is to give a vivid adhere of chapter V. In this post, I just elaborate a small part introduced by a few of section, that is the runtime stack.
