vm

virtual machine thingy

It's turing complete too :)

The destination register is the first one, and the resulting are the arguments.

Number	Instruction	Description	Examples
0	HALT	Stop execution	HALT
1	ADD	Add values in R1 specified registers	ADD R1 R2 R3
2	MULT	Multiply values in specified registers	MULT R1 R2 R2
3	DIV	Divide values in specified registers	DIV R1 R2 R3
4	SET	Set register to operand	SET R1 954
5	PRNT	Print value of register to stdout	PRNT R1
6	NOP	Do nothing	NOP
7	RJMP	Jump to instruction relative to current	RJMP -3 (will jump 3 instructions back)
8	IF	If the specified register equals the register in operand, set IP to second operand	IF R1 R4 R5 (if R1 equals R4 set IP to R5)
9	XOR	XOR the values in specified registers and output to first specified register	XOR R1 R2 R7
10	CFR	Copy from register to register	CFR R3 R5
11	AND	Execute an AND bitwise operation on the values in two registers, and store in the first	AND R5 R1 R1
12	IFN	If the specified register does not equal the register in operand, set IP to second operand	IFN R1 R4 R5 (if R1 does not equal R4 set IP to R5)
13	PUSH	Push number in register to stack	PUSH R1
14	POP	Pop number in stack into register	POP R1

NOTE: To compile, first write the correct ASM, then call vmasm on the file to convert it to instructions. Then, call vm on the instruction file.
