This lecture delves into the essential components of compiler design, covering topics such as the analysis and synthesis model, and the processes of lexical, syntax, and semantic analysis. It outlines the various phases of a compiler and introduces related tools including interpreters, preprocessors, assemblers, linkers, and loaders. Students will gain an understanding of each phase's role, how they interconnect, and the critical tasks they perform in transforming source code into executable programs.

Topics Discussed in Class • Section 1.1: Introduction to Compilers Analysis Synthesis Model • Section 1.2: Lexical Analysis (Also called Scanning), Syntax Analysis, Semantic Analysis • Section 1.3: The phases of Compiler (complete)
Section 1.4: Cousins of Compiler • Interpreters: discussed in detail in first lecture • Preprocessors: They produce input for the compiler. They perform jobs such as deleting comments, include files, perform macros etc. • Assemblers: They are translators for Assembly language. Sometimes the compiler will generate assembly language in symbolic form then hand it over to assemblers. • Linkers: Both compilers and assemblers rely on linkers to collect code separately compiled or assembled in object file into a file that is directly executable. • Loaders: It resolves all relocatable addresses to base address
