In computer science, a compiler-compiler or compiler generator is a programming tool that creates a parser, interpreter, or compiler from some form of formal description of a language and machine. The earliest and still most common form of compiler-compiler is a parser generator, whose input is a grammar (usually in BNF) of a programming language, and whose generated output is the source code of a parser often used as a component of a compiler.
The ideal compiler-compiler takes a description of a programming language and a target instruction set architecture, and automatically generates a usable compiler from them. In practice, the state of the art has yet to reach this degree of sophistication and most compiler generators are not capable of handling semantic or target architecture information.
A typical parser generator associates executable code with each of the rules of the grammar that should be executed when these rules are applied by the parser. These pieces of code are sometimes referred to as semantic action routines since they define the semantics of the syntactic structure that is analyzed by the parser. Depending upon the type of parser that should be generated, these routines may construct a parse tree (or abstract syntax tree), or generate executable code directly.

Write your own compiler in 24 hours by Phil Trelford (@ptrelford) Compiler writers are often seen as the stuff of myth and legend. In this session we'll step behind the proverbial curtain and reveal how compilers actually work. Expect plenty of live code samples, primarily in F#, covering language design and parsing, all-the-way through to emitting code. This session is aimed as a primer for those interested in writing an external DSL, general purpose language or just understanding how these things work. http://www.meetup.com/Norfolk-Developers-NorDev/events/205707742/
What is a Compiler A compiler is a Special Program, that converts the source program written in a high level language into target program which is an Machine language. Compilation process is a sequence of various phases.There are 6 phases of Compiler.They are Lexical Analysis Syntax Analysis Semantic Analysis Intermediate Code Representation Code Optimization & Code Generation These 6 phases of compilers are explained in Detail in this video.

How to Build a Compiler by James Kyle Compilers are all around you: Babel, Handlebars/HTMLBars, Glimmer, Uglify, and more. In this talk we'll walk through every part of a compiler from the parser to the generator. Learn about visitors and traversal, paths, scopes, bindings, and everything else. By the end compilers shouldn't seem like magic, and maybe you'll even want to contribute back to them.
Day 1 - C++ has powerful rules for dealing with low-level program structure. Before a program is ever executed, the compiler determines valuable information about every expression in the source code. The compiler understands exactly how long each object's resources will be needed (lifetime), whether each expression refers to an object that the program has no other way of accessing (rvalueness), and what operations can be performed on each object (type). Using examples from C++98 through C++14, this presentation will demonstrate how to write code that works with the compiler's knowledge to increase robustness, efficiency, and clarity. This presentation will also demonstrate the horrible things that happen when programmers think they can do tasks that are better left to compilers.

During the discussion a bash script was written to quickly compile C++ source and dump the assembly. Five years later and that script has grown into a website relied on by many to quickly see the code their compiler emits, to compare different compilers' code generation and behaviour, to quickly prototype and share code, and investigate the effect of optimization flags. In this talk Matt will not only show you how easy (and fun!) it is to understand the assembly code generated by your compiler, but also how important it can be. He'll expla...

What is compiler ? and why we use compiler? and need of compiler's. Video - Compiler Explained - What is a Compiler ? - Why we use Compiler ? A compiler is a special program that processes statements written in a particular programming language and turns them into machine language or "code" that a computer's processor uses. Typically, a programmer writes language statements in a language such as Pascal or C one line at a time using an editor. How does the compiler works? A compiler is a program that translates the source code for another program from a programing language into executable code. The source code is typically in a high-level programming language (e. g. Pascal, C, C++, Java, Perl, C#, etc.). ... As to how a compiler works, that is indeed complicated. ...
