Principles of compiler design ppt

How a compiler works?
The compiler verifies that the code's syntax is correct, based on the rules for the source language.
This process is also referred to as parsing.
During this step, the compiler typically creates abstract syntax trees that represent the logical structures of specific code elements..
What is lexical analysis in principles of compiler design?
Lexical analysis is the starting phase of the compiler.
It gathers modified source code that is written in the form of sentences from the language preprocessor.
The lexical analyzer is responsible for breaking these syntaxes into a series of tokens, by removing whitespace in the source code..
Why should we learn compiler design?
Compiler design principles provide an in-depth view of translation and optimization process.
Compiler design covers basic translation mechanism and error detection & recovery.
It includes lexical, syntax, and semantic analysis as front end, and code generation and optimization as back-end..

Course Outline

The course will mainly cover topics from the following list (not necessarily in the same order).
1) Compiler structure: analysis-synthesis model of compilation, various phases of a compiler, tool based approach to compiler construction..
2) Lexical analysis: interface with input, parser and symbol table, token, lexeme and patterns.

Course Project

The course project gives you a chance to apply the concepts learnt in the class to build a prototype compiler.
You will be required to implement various phases of a compiler, and perform an experimental evaluationof your implementation.
1) Project will be done in groups.
The maximum (and preferable) size of a group will be threestudents.

What was the impact of the first compiler?

The whole new field of compiler design was started The first compiler had a huge impact on the programming languages and computer science.
The whole new field of compiler design was started Modern compilers preserve the basic structure of the Fortran I compiler !!! .

What does a compiler do?

8 A compiler translates a program written in a high-level programming language that is suitable for human programmers into the low-level machine language that is required by computers + spots and reports obvious programmer mistakes

What is a compiler design model?

Compiler design is one of the places where theory has had the most impact on practice

Models that have been found useful include automata, grammars, regular expressions, trees, and many others

4 Code Optimization

Although code cannot truly be "optimized," the sci ence of improving the efficiency of code is both complex and very impor tant
