This directory implements a memory management library that hides the
operating system dependencies. It supports the allocation of memory
objects aligned to MAP_PAGE_SZB byte boundries (see mapping.h).
The following routines are exported:
void MEM_InitMemory ();
mem_obj_t *MEM_AllocMemObj (word_t szb);
void MEM_FreeMemObj (mem_obj_t *obj);
There are three different implementations:
1) a version that uses the SVR4 mmap mechanism to allocate chunks of memory.
2) a version that uses the MACH vm_allocate call to allocate chunks of memory.
3) a version that layers memory chunk management on top of the brk system
call. This version also provides an implementation of malloc.
The version of malloc was retrieved from g.oswego.edu:/pub/misc/malloc.c
