Download A Practical Approach to Compiler Construction by Des Watson PDF

By Des Watson

This ebook presents a practically-oriented advent to high-level programming language implementation. It demystifies what is going on inside a compiler and stimulates the reader's curiosity in compiler layout, a necessary element of desktop technology. Programming language research and translation suggestions are utilized in many software program program areas.

A functional method of Compiler Construction covers the basic rules of the topic in an available manner. It offers the required heritage idea and indicates the way it may be utilized to enforce entire compilers. A step by step process, according to a customary compiler constitution is followed, proposing updated options and examples. ideas and designs are defined intimately to lead the reader in imposing a translator for a programming language.

A basic high-level language, loosely in line with C, is used to demonstrate features of the compilation technique. Code examples in C are integrated, including dialogue and representation of the way this code could be prolonged to hide the compilation of extra complicated languages. Examples also are given of using the flex and bison compiler construction instruments. Lexical and syntax research is roofed intimately including a entire insurance of semantic research, intermediate representations, optimisation and code iteration. Introductory fabric on parallelisation can be included.

Designed for private research in addition to to be used in introductory undergraduate and postgraduate classes in compiler layout, the writer assumes that readers have a cheap competence in programming in any high-level language.

Sample text

Care is needed to avoid omission or ambiguity and to prevent the specification from becoming overly long. There is a real danger of assuming that the semantics of programming language constructs are “obvious”. This is far from being true—there are many examples of real programming language features that are often misinterpreted by the programmer and sometimes mis-implemented by the compiler writer. This book takes the easy route and avoids issues concerned with the formal specification of semantics.

However, there are potential problems that may arise because of software or even hardware errors in that reference implementation which, strictly speaking, should be followed by all other implementations. A third approach, and an approach used widely in the specification of popular languages, is to specify the semantics using a natural language. Here, text in a natural language such as English is used to describe the semantic rules of the programming language. Care is needed to avoid omission or ambiguity and to prevent the specification from becoming overly long.

To avoid this ambiguity, the lexical analyser may be expected to return the token type identifier instead of identifier when t has already been defined in a typedef declaration. And to do this, there must be some communication back from the lexical analyser to the syntax analyser to allow the lexical analyser to determine the nature of t. This is messy, and it is a consequence of the way in which the C grammar is defined. We will revisit this problem in Chap. 5. Integer and floating point constants may appear fairly straightforward but there are some important issues to address.
