[Flashforth-devel] C stack - passing the params (pic24/33)

[pito <pi...@vo...>]

In the C example we pass a single 16bit short param:

        mov     [W14], W0
        .extern C4add
        call    _C4add
        mov     W0, [W14]

So my current understanding is to pass 4 shorts (2 floats) would mean something like this:

( f1l  f1h  f2l  f2h  --  fl  fh )

        mov     [W14--], W0  ; f2h
	mov     [W14--], W1  ; f2l
	mov     [W14--], W2  ; f1h
	mov     [W14],   W3  ; f1l
        .extern Cfadd
        call    _Cfadd
        mov     W0, [W14++]  ; fl
	mov     W1, [W14]      ; fh

Am I correct??
Thanks,
