Pour la mise en \u0153uvre dans Fedora 33 pr\u00e9vu<\/a><\/noindex> modification<\/a><\/noindex> R\u00e8gles d'application des compilateurs dans la distribution, selon lesquelles le compilateur pour la construction du paquet peut \u00eatre s\u00e9lectionn\u00e9 en fonction des recommandations et des pr\u00e9f\u00e9rences du projet principal (upstream). Actuellement, Fedora impose strictement l'utilisation de GCC pour la construction de tous les paquets, sauf dans les cas o\u00f9 le paquet ne peut \u00eatre construit qu'avec Clang\/LLVM.<\/p>\n

Le motif de la possibilit\u00e9 de construction avec Clang est que certains projets, par exemple, Firefox<\/a><\/noindex> et Chromium<\/a><\/noindex>, lors de leur d\u00e9veloppement, utilisent Clang comme compilateur principal, et les constructions bas\u00e9es sur celui-ci sont mieux test\u00e9es. L'utilisation de Clang pour de tels paquets permet d'\u00e9viter de rencontrer des erreurs lors de la construction avec GCC ainsi que la n\u00e9cessit\u00e9 de concilier les corrections de ces erreurs avec le projet principal. La construction avec GCC a un effet positif sur la portabilit\u00e9 du code d\u00e9velopp\u00e9 avec Clang, mais cr\u00e9e une charge importante pour les mainteneurs et retarde la publication des mises \u00e0 jour (par exemple, Mozilla interdit<\/a><\/noindex> d'utiliser la marque d\u00e9pos\u00e9e Firefox lors de l'application de patchs tiers, il est donc n\u00e9cessaire de d'abord obtenir l'inclusion des patchs dans la composition principale et de publier la mise \u00e0 jour uniquement apr\u00e8s l'apparition des corrections dans l'upstream).<\/p>\n

Il est not\u00e9 qu'il serait logique d'utiliser Clang pour les paquets pour lesquels ce compilateur convient mieux et est utilis\u00e9 dans le projet principal. Pour de tels paquets, il serait possible de r\u00e9duire la charge de maintenance si la pr\u00e9paration des paquets est effectu\u00e9e par des repr\u00e9sentants du projet principal. Si la construction du paquet est effectu\u00e9e par un repr\u00e9sentant de la communaut\u00e9, il convient de proposer au mainteneur la possibilit\u00e9 de choisir le compilateur. Pour les paquets dont les projets principaux ne privil\u00e9gient pas un compilateur particulier, il est recommand\u00e9 de maintenir le statu quo (de construire avec GCC comme auparavant). L'auteur de la proposition est Jeff Law de Red Hat, qui fait partie des mainteneurs de GCC et de Binutils.<\/p>\n
