Saving/restoring registers is possible with PUSH and POP instructions.
jump location - continue running at instruction number given by location
jumpi reg1 - continue running at instruction number in reg1
call location - save current instruction location+1, continue execution at instruction nr given by location
calli reg1 - save current instruction location+1, continue execution at instruction number in reg1
syscall value - do a systemcall identified by call number
