Kaffe Memory Management

[Johan Andersson]

Hi.


Why does Kaffe (linux) uses sbrk(..) to allocate memory. According to the man. pages for sbrk(..) it is not very feasible. Why doesn't Kaffe use malloc(..)?

In gc_small_alloc(..) and gc_large_alloc(..):

info->funcs=(unitp8*)GCBLOCK2BASE(info);
info->state=(unitp8*)(info->funcs+nr);
info->data=....;
.
What happens here? Where do these pointers point to. Memory addresses in the heap or to addresses in the space allocated by malloc for a number of gc_blocks (which is used by the gc_primary_freelist).

The bottom line is, what of the gc_block is put on the heap?
