[cc65] Optimization possible?

Hi all,

Accidently I found the piece of code below. Is it possible to optimize
the ldx L000F out? I don't know if the compiler knows that the value
isn't used later.

(v is a static signed char, compiled with -O)

;
; while (--v >= 0)
;
L0012:  dec     L000F
        ldx     L000F
        bmi     L0013
;
; array[v] = 0;
;
        ldy     L000F
        lda     #$00
        sta     _array,y
;
; }

Regards,

Thomas
