IFF the processor doesn't reorder them in hardware, which on some processors is visibly out of order when viewed from an I/O device or another CPU. You can stop the compiler but not the CPU - and some processors will certainly speculatively load across conditionals, reorder writes etc - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
