CA 2465626

For each process a stack data structure that includes two stacks, which are joined at their bases, is created. The two stacks include a normal stack, which grows downward, and an inverse stack, which grows upward. Items on the stack data structure are segregated into protected and unprotected classes. Protected items include frame pointers and return addresses, which are stored on the normal stack. Unprotected items are function parameters and local variables. The unprotected items are stored on the inverse stack.

Pour chaque processus, une structure de données en pile, comprenant deux piles reliées à leur base, est créée. Ces deux piles comprennent une pile normale, qui s'accumule vers le bas, et une pile inversée, qui s'accumule vers le haut. Les articles de la structure de données en pile sont divisés en types, protégés et non protégés. Les articles protégés comprennent les adresses de séquence et les adresses de retour, qui sont stockées sur la pile normale. Les articles non protégés sont des paramètres de fonctionnement et des variables locales, et ils sont stockés sur la pile inversée.
