As an example of such a construct is the forward declaration in Pascal. Some programming languages have been designed specifically to be compiled with one-pass compilers. Sometimes single pass compiler is called narrow compiler, which points to the limited scope of a one-pass compiler.

In other words, a single-pass compiler does not вЂlook backвЂ™ the code it has previously processed.

Single pass: In computer programming, a single pass or one-pass compiler is a compiler that scans through the source code of each compilation unit only once.

13.1 Block Diagram of Compiler 13.2 Types of CompilerД¬ompilers are classified mainly into three types according to their operational process. The block diagram of compiler is shown in Fig. In the operational process of a compiler it reports the programmer the presence of errors in the source program. In relation to compiler the source language is human readable language called High Level Language and target language is machine readable code called machine level language. 13.1 DefinitionД¬ompiler is a program that takes a program written in a source language and translates it into an equivalent program in a target language. Compiler needs a vast discussion, but in this section we shall discuss only those parts which are directly related to Automata.

To learn different phases of compiler we need the knowledge of Finite Automata, Regular Expression, Context Free Grammar etc. Compiler is basically built on the knowledge of Automata. But this is not the only job for a compiler, its job is much wider than error checking. Most of the students have a wrong idea that compilation is required only to check the errors. As an example, for C and C++ we have found Turbo C compiler, for Java we have seen Java compiler and so on. When we have learnt different programming languages like C, C++ or Java we got familiar with the term compiler. Let's see how it works out.13 Basics of Compiler Design Introduction I thought it would be a good way to learn by typing the whole content word for word. It would be an additional advantage if you have had prior exposure to Assembly Programming. This tutorial requires no prior knowledge of compiler design but requires basic understanding of at least one programming language such as C, Java, etc. Enthusiastic readers who would like to know more about compilers and those who wish to design a compiler themselves may start from here. This tutorial is designed for students interested in learning the basic principles of compilers. This is known as Language Processing System.

These programs are then fed into a series of tools and OS components to get the desired code that can be used by the machine. So we write programs in high-level language, which is easier for us to understand and remember. The hardware understands a language, which humans cannot understand. We have learnt that any computer system is made of hardware and software. It would be a difficult and cumbersome task for computer programmers to write such codes, which is why we have compilers to write such codes. To instruct, the hardware codes must be written in binary format, which is simply a series of 1s and 0s. Binary language has only two alphabets, 0 and 1.

Hardware understands instructions in the form of electronic charge, which is the counterpart of binary language in software programming. Hardware is just a piece of mechanical device and its functions are being controlled by a compatible software. Why to Learn Compiler design?Д¬omputers are a balanced mix of software and hardware. It includes lexical, syntax, and semantic analysis as front end, and code generation and optimization as back-end. Compiler design covers basic translation mechanism and error detection & recovery. It is also expected that a compiler should make the target code efficient and optimized in terms of time and space.Д¬ompiler design principles provide an in-depth view of translation and optimization process. A compiler translates the code written in one language to some other language without changing the meaning of the program.
