Clairvic

ByteCode language aimed at fast cross-platform execution and minimal executable-sizes

FULL DISCLAIMER: This is some pretty old code I wrote in an entirely experimental manner, trying to avoid caveats of the STL - the code might not be clean, in fact it might not even work. I'm uploading this for a friend of mine who is going to use it.

Basics

Clairvic only has a single memory and a stack. Most of the "computing" only ever happens in intrinsic thus reducing the size of the executable by a lot. The first three bytes contain the magic number 'CLV', from then on everything is executed, starting at the 4th byte.

Operation Codes

	ASM-equivalent	Arguments (if any)
0	call	Location	Sets the InstructionPointer to the location Negative values refer to Intrinsics Automatically creates stackframes Pass arguments through the stack, first in is the first out
1	ret		like ret in assembler
2	hlt	<1 Byte> error Code
3	push		Pushes workreg into stack
4	pop		Pops the top entry in the stack to workreg
5	mov	index in stackframe	Gets the item from the stackframe at that index into workreg
6	mov		sets workreg to
7	mov	pointer	Moves a word-value in the program code pointed to by into workreg
8	mov	pointer	Puts the current value of workreg into the program code at a position pointed by
9	mov	index in stackframe	Sets the item from the stackframe at that index to workreg
10	jne	pointer	if workreg is zero, continues, else jumps (no stackframe created) to
11			Discards the top value from the stack
12	jmp	Pointer
13	je	Pointer	inverse of jne

This has to be enough for now, I'll update this list eventually
