HelloSilicon
HelloSilicon est un guide de programmation et un tutoriel pour écrire et déboguer du code assembleur 64 bits de bas niveau spécifiquement pour les processeurs Apple Silicon. Il sert de référence d'architecture pour interagir avec les services du noyau macOS et iOS en utilisant des appels système et des registres matériels.
Le projet fournit des instructions spécialisées sur l'interfaçage de fonctions étrangères (FFI) pour faire le pont entre l'assembleur et des langages de haut niveau comme C ou Python. Il inclut également une boîte à outils pour configurer les binaires Mach-O et compiler des binaires universels et des bibliothèques dynamiques pour la compatibilité inter-matériel.
Le matériel couvre la programmation système de bas niveau, incluant l'adressage mémoire, les conventions d'appel et l'utilisation de débogueurs pour inspecter les registres et la mémoire.
