RUN-Time Organization Compiler phase- Before writing a code generator, we must decide how to marshal the resources of the target machine (instructions, storage, and system software) in order to implement the source language. This is called run-time organization

TAC Three address code Three-address code (TAC) will be the intermediate representation used in our Decaf compiler. It is essentially a generic assembly language that falls in the lower-end of the mid-level IRs. Many compilers use an IR similar to TAC. It is a sequence of instructions, each of which can have at most three operands. The operands could be

背诵篇章 01 The Language of Music A painter hangs his or her finished pictures on a wall, and everyone can see it. A composer writes a work, but no one can hear it until it is performed. Professional singers and players have great responsibilities, for the composer is utterly dependent on them. A student of music needs as long and as arduous a training to become

汇编语言是直接在硬件之上工作的编程语言,首先要了解硬件系统的结构,才能有效 地应用汇编语言对其编程。在本章中,对硬件系统结构的问题进行一部分的探讨,以使后 续的课程可在-个好的基础上进行。当课程进行到要补充新的基础知识关于编程结构或 其他的)时候,冉对相关的基础知识进行介绍和探讨。本书的原则是,以后用到的知识,以 后再说
