Compiler Design Phases Of Compiler Pdf Compiler Parsing The back end takes over from there, handling optimization, code generation, and assembly. phases of compiler 1. lexical analysis lexical analysis is the first phase of a compiler, responsible for converting the raw source code into a sequence of tokens. a token is the smallest unit of meaningful data in a programming language. Phase 1: lexical analysis lexical analysis is the first phase when compiler scans the source code. this process can be left to right, character by character, and group these characters into tokens. here, the character stream from the source program is grouped in meaningful sequences by identifying the tokens. it makes the entry of the corresponding tickets into the symbol table and passes that.

Lexical analyzer (scanner): the scanner is the first phase that works as interface between the compiler and the source language program and performs the following functions:. The information about data objects is collected by the early phases of the compiler lexical and syntactic analyzers. the data structure used to record this information is called as symbol table. Unit i compiler design – scsa1604 unit 1 lexical analysis structure of compiler – functions and roles of lexical phase – input buffering – representation of tokens using regular expression – lex – properties of regular expression – finite automata – regular expression to finite automata – nfa to minimized dfa.
