No

Yes, you manage them yourself. Sljit is more like a real asm but
it's a barebone asm. There are only basic instructions available
(mov, arith plus few more). You can work with 3+2 scratch registers
and 3+2 "saved" registers. You have access to the stack but you
can't use it if you want to wrap your function into a C function
pointer. You can only use first three "saved" registers to pass
arguments.
