Compiler Design: principles by aa Puntambekar – The Importance of Principles of Compiler Design is well known in computer engineering fields. The Book is structured to cover the key aspects of the subject Principles of compiler design. This book was written by A.A Putambekar and he uses very simple language to describe difficult concepts. Compiler Design 10 A compiler can broadly be divided into two phases based on the way they compile. Analysis Phase Known as the front-end of the compiler, the analysis phase of the compiler reads the source. Compiler Building Tutorial. You should be able to design and build your own working compiler. It will not be the world’s best. (PDF) version Long ago (2000. This Compiler Design pdf notes (CD pdf notes) free download book starts with the topics covering Phases of Compilation, Context free grammars, Shift Reduce parsing, LR and LALR parsing, Intermediate forms of source Programs, Flow graph, Consideration for Optimization, Flow graph, Object code forms, Etc.

All books are in clear copy here, and all files are secure so don't worry about it. This site is like a library, you could find million book here by using search box in the header. If your compiler isn’t in the foregoing list, but is ANSI compatible, then your best bet is probably to pretend you’re the Microsoft compiler by adding the following lines at the top of debug.h: #define MSDOS 1 #define MSCVER 700 Some massaging might still be necessary, however. September 11, 1997 -5- Compiler Design in C. Compiler design could be included while a v oiding features that led to burdensome but ob vious detail. It also allo ws us to illustrate ho w a compiler writer deriv es information ab out a language, and pro vides an example of an informal but relativ ely precise language de nition. W e c hose the mac hine language of IBM 370 and its imitators.

Compiler is a software which converts a program written in high level language (Source Language) to low level language (Object/Target/Machine Language).

• Cross Compiler that runs on a machine ‘A’ and produces a code for another machine ‘B’. It is capable of creating code for a platform other than the one on which the compiler is running.
• Source-to-source Compiler or transcompiler or transpiler is a compiler that translates source code written in one programming language into source code of another programming language.

Language processing systems (using Compiler) –
We know a computer is a logical assembly of Software and Hardware. The hardware knows a language, that is hard for us to grasp, consequently we tend to write programs in high-level language, that is much less complicated for us to comprehend and maintain in thoughts. Now these programs go through a series of transformation so that they can readily be used machines. This is where language procedure systems come handy.

• High Level Language – If a program contains #define or #include directives such as #include or #define it is called HLL. They are closer to humans but far from machines. These (#) tags are called pre-processor directives. They direct the pre-processor about what to do.
• Pre-Processor – The pre-processor removes all the #include directives by including the files called file inclusion and all the #define directives using macro expansion. It performs file inclusion, augmentation, macro-processing etc.
• Assembly Language – Its neither in binary form nor high level. It is an intermediate state that is a combination of machine instructions and some other useful data needed for execution.
• Assembler – For every platform (Hardware + OS) we will have a assembler. They are not universal since for each platform we have one. The output of assembler is called object file. Its translates assembly language to machine code.
• Interpreter – An interpreter converts high level language into low level machine language, just like a compiler. But they are different in the way they read the input. The Compiler in one go reads the inputs, does the processing and executes the source code whereas the interpreter does the same line by line. Compiler scans the entire program and translates it as a whole into machine code whereas an interpreter translates the program one statement at a time. Interpreted programs are usually slower with respect to compiled ones.
• Relocatable Machine Code – It can be loaded at any point and can be run. The address within the program will be in such a way that it will cooperate for the program movement.
• Loader/Linker – It converts the relocatable code into absolute code and tries to run the program resulting in a running program or an error message (or sometimes both can happen). Linker loads a variety of object files into a single file to make it executable. Then loader loads it in memory and executes it.

Phases of a Compiler –
There are two major phases of compilation, which in turn have many parts. Each of them take input from the output of the previous level and work in a coordinated way.

Analysis Phase – An intermediate representation is created from the give source code :

1. Lexical Analyzer
2. Syntax Analyzer
3. Semantic Analyzer
4. Intermediate Code Generator

Lexical analyzer divides the program into “tokens”, Syntax analyzer recognizes “sentences” in the program using syntax of language and Semantic analyzer checks static semantics of each construct. Intermediate Code Generator generates “abstract” code.
Synthesis Phase – Equivalent target program is created from the intermediate representation. It has two parts :

5. Code Optimizer
6. Code Generator

Code Optimizer optimizes the abstract code, and final Code Generator translates abstract intermediate code into specific machine instructions.
