Lecture # 2

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
