<<I think the goal and intent, for Ada and C as well, is to say that the compiler will generate what is possible from assembly code written by an expert on the platform, using the best fitting access that is possible. >>
Ah ha! But then look again at my 16-bit example, an expert assembly langauge programmer will use a 32 bit load if efficiency is not an issue (and it does not matter if there are extra bits around), but a 16-bit load if the hardware for some reason requires it. How is the poort C compiler to distinguish these cases automatically? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
