I am interested in understanding some basic things about SLJIT.

a) Does it have a register allocator?
b) Does the api need the user to manage virtual registers or is it
automatic like in LLVM or NanoJIT? By this I mean in NanoJIT one can
write something like this (this is shown in the format used by its
assembler):

two = immi 2
three = immi 3
res = addi two three
reti res

As you can see above the user does not have to maintain virtual
registers - you just operate on the result of instructions. This is
similar to LLVM's api, as well as libjit.
