Summary: bad code for unsigned char * xdata

Initial Comment:
// sdcc -mmcs51 -p8052 --debug --all-callee-saves
--stack-auto -c test.c
// using sdcc 2.3.7

unsigned char * xdata ptr = ((void *) 0);

unsigned char foo(unsigned int offset)
{
        unsigned char value;

        value = ptr[offset];

        return value;
}


;test.c:9: value = ptr[offset];
;     genAssign
        mov     dptr,#_ptr
        movx    a,@dptr
        mov     r4,a
        inc     dptr
        movx    a,@dptr
        mov     r5,a
        inc     dptr
        movx    a,@dptr
        mov     r6,a


Shouldn't ptr be a generic pointer???
