Component Object ModelComponent Object Model (abr. COM) est une technique de composants logiciels développée par Microsoft et DEC, depuis 1994, populaire sur Windows et également disponible sur les systèmes d'exploitation OpenVMS, Tru64 ainsi que d'autres Unix. Utilisée pour mettre en œuvre OLE et ActiveX, COM est dépassé depuis 2009 par le Framework .NET de Microsoft. Les technologies COM regroupent OLE, COM+, Distributed COM et ActiveX.
Makevignette|Capture d'écran du logiciel Make Make est un logiciel qui construit automatiquement des fichiers, souvent exécutables, ou des bibliothèques à partir d'éléments de base tels que du code source. Il utilise des fichiers appelés makefile qui spécifient comment construire les fichiers cibles. À la différence d'un simple script shell, make exécute les commandes seulement si elles sont nécessaires. Le but est d'arriver à un résultat (logiciel compilé ou installé, documentation créée, etc.
Linker (computing)In computing, a linker or link editor is a computer system program that takes one or more s (generated by a compiler or an assembler) and combines them into a single executable file, library file, or another "object" file. A simpler version that writes its output directly to memory is called the loader, though loading is typically considered a separate process. Computer programs typically are composed of several parts or modules; these parts/modules do not need to be contained within a single , and in such cases refer to each other by means of symbols as addresses into other modules, which are mapped into memory addresses when linked for execution.
Translation de codeEn informatique, la translation de code est une technique d'émulation consistant à traduire (de l'anglais « to translate », traduire) le jeu d'instructions d'une architecture source vers le jeu d'instructions d'une architecture destination. On distingue deux types de translation de code : la translation statique, dans ce cas un fichier exécutable de la machine source est intégralement traduit en un fichier exécutable de la machine destination ; la translation dynamique (ou compilation à la volée), dans ce cas les instructions de la machine source sont traduites en instructions de la machine cible au moment même de leur exécution.
Object code optimizerAn object code optimizer, sometimes also known as a post pass optimizer or, for small sections of code, peephole optimizer, forms part of a software compiler. It takes the output from the source language compile step - the object code or - and tries to replace identifiable sections of the code with replacement code that is more algorithmically efficient (usually improved speed). The earliest "COBOL Optimizer" was developed by Capex Corporation in the mid 1970s for COBOL.
Multi-pass compilerA multi-pass compiler is a type of compiler that processes the source code or abstract syntax tree of a program several times. This is in contrast to a one-pass compiler, which traverses the program only once. Each pass takes the result of the previous pass as the input, and creates an intermediate output. In this way, the (intermediate) code is improved pass by pass, until the final pass produces the final code. Multi-pass compilers are sometimes called wide compilers, referring to the greater scope of the passes: they can "see" the entire program being compiled, instead of just a small portion of it.
Probabilistic context-free grammarGrammar theory to model symbol strings originated from work in computational linguistics aiming to understand the structure of natural languages. Probabilistic context free grammars (PCFGs) have been applied in probabilistic modeling of RNA structures almost 40 years after they were introduced in computational linguistics. PCFGs extend context-free grammars similar to how hidden Markov models extend regular grammars. Each production is assigned a probability.
Peephole optimizationPeephole optimization is an optimization technique performed on a small set of compiler-generated instructions; the small set is known as the peephole or window. Peephole optimization involves changing the small set of instructions to an equivalent set that has better performance.
Grammaire LLvignette|300x300px| La grammaire C n’est pas LL (1): la partie inférieure montre un analyseur qui a digéré les jetons " int v ;main(){ " et qui concerne le choix d’une règle pour dériver le non-terminal " Stmt ". En regardant uniquement le premier jeton d'anticipation " v ", il ne peut pas choisir laquelle des deux alternatives pour " Stmt " choisir, étant donné que deux suites d'entrées sont possibles. Ils peuvent être distingués en jetant un coup d'œil sur le deuxième jeton d'anticipation (fond jaune).
Programming toolA programming tool or software development tool is a computer program that software developers use to create, debug, maintain, or otherwise support other programs and applications. The term usually refers to relatively simple programs, that can be combined to accomplish a task, much as one might use multiple hands to fix a physical object. The most basic tools are a source code editor and a compiler or interpreter, which are used ubiquitously and continuously.
