r ### Arithmetic Operations - ADD ; Add top two numbers - SUB ; Subtract - MUL ; Multiply - DIV ; Divide - REMAINDER ; Modulo operation ### Comparison Operations - EQ ; Generic equality test - NUM_EQ ; Numeric equality - NUM_LT ; Less than - NUM_GT ; Greater than ### Control Flow - JUMP offset ; Unconditional jump - JUMP_IF_FALSE offset ; Conditional jump - JUMP_IF_TRUE offset ; Conditional jump ### Type Operations - TYPE_OF ; Get type of value - IS_PAIR ; Test if value is pair - IS_NUMBER ; Test if value is number - IS_SYMBOL ; Test if value is symbol ## Example Instruction Sequences ### Function Definition ```scheme (define (add1 x) (+ x 1)) ``` Compiles to: ``` MAKE_FUNCTION L1 STORE_LOCAL 0 JUMP L2 L1: LOAD_LOCAL 0 ; Load x PUSH_CONST 1 ADD RETURN L2: ``` ### List Creation ```scheme (cons 1 (cons 2 '())) ``` Compiles to: ``` PUSH_CONST 1 PUSH_CONST 2 PUSH_CONST nil CONS CONS ``` ### Closure Creation ```scheme (let ((x 1)) (lambda (y) (+ x y))) ``` Compiles to: ``` PUSH_CONST 1 ; Push initial value of x MAKE_FUNCTION L1 ; Create function body MAKE_CLOSURE 1 ; Create closure capturing x JUMP L2 L1: LOAD_FREE 0 ; Load captured x LOAD_LOCAL 0 ; Load parameter y ADD RETURN L2: ``` ## Implementation Notes 1. The VM should implement proper tail-call optimization using the TAIL_CALL instruction. 2. Garbage collection can be implemented using a simple mark-and-sweep collector, scanning the stack and heap for reachable objects. 3. For efficiency, common constants (small integers, nil, etc.) can be preallocated and shared. 4. The environment model uses static scope, with closures capturing their creation environment. 5. Function calls maintain their own stack frame with local variables and operand stack.
