Actually, I could never get GCC to avoid a divide on sparc64 for certain kinds of pointer arithmetic when the elements were not a power of two. It probably has something to do with signedness. I think I narrowed is down to the fact that you can't legally replace a signed divide with shift/add/subtract. But I could be remembering things wrong. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
