The list of instructions on the web doesn't appear to have "setn", 
though it shows up in insns.def.

Also, does "setn" pop the value at the top when it sets the nth element 
in the stack? It didn't seem clear from the instruction definition:

DEFINE_INSN
setn
(num_t n)
(..., VALUE val)
(VALUE val) // inc += 0
{
     GET_SP()[-n] = val;
}
