I thought split stacks were just the name of the feature of having a
non-necessarily contiguous stack which gets allocated on demand. You
will obviously need some kind of malloc() to create a stack for you, but
as the compiler will need to know about it, probably not anyone works.
There may be some kind of stack_alloc(), I'd take a look at how does
pthread_create() make its stack.

Good luck
