hi all:

       The codes is:

static int match(int len,const char * name,struct dir_entry * de)

{

        register int same __asm__("ax");

        if (!de || !de->inode || len > NAME_LEN)

                return 0;

        if (len < NAME_LEN && de->name[len])

                return 0;

        __asm__ ("cld\n\t"

                "fs ; repe ; cmpsb\n\t"

                "setz %%al"

                :"=a" (same)

                :"0" (0),"S" ((long) name),"D" ((long) de->name),"c" (len)

                :"cx","di","si");

        return same;

}

When I make it, the error messages is:

namei.c:35: error: can't find a register in class ‘AREG’ while reloading ‘asm’

This is why? 

Thank you
