Cours Langage C/C++ Mémoire et allocation dynamique
La pile (stack) est un espace mémoire réservé au stockage des variables désallouées automatiquement. Sa taille est limitée mais on peut la régler (appel
Allocation de la mémoire
Allocation de la mémoire dans le tas (heap). Allocation de la mémoire dans la pile (stack) malloc utilise les fonctions de bas niveau brk() et sbrk().
Scope Stack Allocation
Heap allocation is very expensive With a global heap memory fragments ... Temporary stuff allocated next to semi-permanent stuff (system arrays etc) ...
Garbage Collection Can Be Faster Than Stack Allocation
30 juin 1986 Many modern programming environments use heap storage with garbage collection. Allocated cells that are not reachable (via a chain of pointers) ...
Faster closures in Scala via Stack-allocation

There are also persuasive arguments in favor of heap allocation. In the Standard ML compiler [AM87] all closures are allocated in the heap. It appears that
Global Stack Allocation –
Register allocation is a critical part of any compiler yet register allocation for stack machines has received rela- tively little attention in the past.
