executable_loader's Introduction
Nume: Florin Postolache Grupă: 335CC Tema 3 Loader de Executabile Imi cer scuze ca scriu README-ul in romana dar am comentarii in engleza. Organizare: Nu pot sa zic ca am adaugat nu stiu ce structuri ajutatoare pentru tema aceasta. Singurul lucru adaugat a fost cate un vector pentru fiecare segment care sa imi spuna daca o anumita pagina din acel segment este deja mapata sau nu. Abordarea generala cred ca a fost destul de directa. Am incercat sa scriu cat mai putine linii de cod dar in acelasi timp am incercat sa nu fac codul foarte greu de inteles. Sper ca am reusit. Consider ca tema este chiar foarte utila, interesanta si usurica dupa ce ai inteles cateva chestii de la curs. Mi-a placut. Cred ca mai bine de atat nu se putea. Implementare Am implementat intregul enunt. Nu exista functionalitati extra. Dificultatea cea mai mare a fost sa inteleg mai bine cum sa tratez cazul special in care trebuie sa zeroizez toata zona aceea din .bss. Cum se compilează și cum se rulează? Executabilul se compileaza folosind comanda make din folderul cu tema. Dupa compilare se va crea o biblioteca dinamica care va trebui mutata in fisierul de checker. Acest executabil nu se ruleaza singur. El este incarcat la nevoie de catre checker pentru a rula testele.
