Linus Torvalds s'est joint<\/a><\/noindex> \u00e0 la discussion capacit\u00e9s<\/a><\/noindex> de l'ajout de support pour le d\u00e9veloppement en Rust dans le noyau Linux. Josh Triplett d'Intel, qui travaille sur le projet<\/a><\/noindex> pour amener le langage Rust \u00e0 un niveau \u00e9quivalent \u00e0 celui du langage C dans le domaine de la programmation syst\u00e8me, a propos\u00e9<\/a><\/noindex> \u00c0 la phase initiale, ajouter une option dans Kconfig pour le support de Rust, qui ne entra\u00eenerait pas l'ajout aux d\u00e9pendances du compilateur Rust lors de l'ex\u00e9cution de la compilation en modes «make allnoconfig» et «make allyesconfig», et permettrait d'exp\u00e9rimenter plus librement avec le code Rust. Une astuce similaire a \u00e9t\u00e9 mise en \u0153uvre lors de l'ajout<\/a><\/noindex> dans le noyau du support exp\u00e9rimental pour la construction avec Clang en mode d'optimisation \u00e0 l'\u00e9tape de liaison (LTO, Link Time Optimization), apr\u00e8s quoi il est pr\u00e9vu d'ajouter aussi le support<\/a><\/noindex> la construction avec protection de l'ex\u00e9cution des commandes (CFI<\/a><\/noindex>, Control-Flow Integrity).<\/p>\n

Linus n'a pas \u00e9t\u00e9 d'accord et a exprim\u00e9 ses craintes que le support initial de Rust ne soit pas test\u00e9 lors de la construction et qu'il risque de s'enliser dans un marasme o\u00f9 un petit groupe de d\u00e9veloppeurs int\u00e9ress\u00e9s v\u00e9rifie le code seulement dans leurs conditions sp\u00e9cifiques et ajoute des \u00e9l\u00e9ments incorrects, car ils restent cach\u00e9s et ne ressortent pas lors des tests du noyau dans d'autres environnements. <\/p>\n

Selon Linus, le premier pilote Rust devrait \u00eatre propos\u00e9 dans un format simple, o\u00f9 les \u00e9checs seraient \u00e9vidents et faciles \u00e0 d\u00e9tecter. Pour simplifier les tests, il a recommand\u00e9 d'agir comme pour la v\u00e9rification des versions du compilateur C et des drapeaux pris en charge \u2014 v\u00e9rifier la pr\u00e9sence du compilateur Rust sur le syst\u00e8me et inclure son support si celui-ci est install\u00e9. <\/p>\n
