Rust (langage)Rust est un langage de programmation compilé multi-paradigme conçu et développé par Mozilla Research depuis 2010. Il a été conçu pour être « un langage fiable, concurrent, pratique », supportant les styles de programmation purement fonctionnel, modèle d'acteur, procédural, ainsi qu'orienté objet sous certains aspects. En 2020, ses domaines de prédilection sont la programmation système, les applications en ligne de commande, les applications Web via WebAssembly, les services réseaux et les systèmes embarqués.
Dead-code eliminationIn compiler theory, dead-code elimination (DCE, dead-code removal, dead-code stripping, or dead-code strip) is a compiler optimization to remove dead code (code that does not affect the program results). Removing such code has several benefits: it shrinks program size, an important consideration in some contexts, and it allows the running program to avoid executing irrelevant operations, which reduces its running time. It can also enable further optimizations by simplifying program structure.
ClangClang est un compilateur pour les langages de programmation C, C++ et Objective-C. Son interface de bas niveau utilise les bibliothèques LLVM pour la compilation. C'est un logiciel libre issu d'un projet de recherche universitaire et distribué selon les termes de la licence Open Source NCSA/Université de l'Illinois. Son but est de proposer une alternative à GCC. En 2005, Apple utilise LLVM dans de nombreux projets commerciaux, dont l'iOS SDK et Xcode 3.1.
Undefined behaviorIn computer programming, undefined behavior (UB) is the result of executing a program whose behavior is prescribed to be unpredictable, in the language specification to which the computer code adheres. This is different from unspecified behavior, for which the language specification does not prescribe a result, and implementation-defined behavior that defers to the documentation of another component of the platform (such as the ABI or the translator documentation).
Optimizing compilerIn computing, an optimizing compiler is a compiler that tries to minimize or maximize some attributes of an executable computer program. Common requirements are to minimize a program's execution time, memory footprint, storage size, and power consumption (the last three being popular for portable computers). Compiler optimization is generally implemented using a sequence of optimizing transformations, algorithms which take a program and transform it to produce a semantically equivalent output program that uses fewer resources or executes faster.
