    hi,
            static inline char * strcpy(char * dest,const char *src)
    {
    int d0, d1, d2;
    __asm__ __volatile__(
            "1:\tlodsb\n\t"
            "stosb\n\t"
            "testb %%al,%%al\n\t"
            "jne 1b"
            : "=&S" (d0), "=&D" (d1), "=&a" (d2)
            :"0" (src),"1" (dest) : "memory");
    return dest;
    }
    Here " & ", in " =&S" is what meaning.
