This is true in the case of externally-visible stuff. I think the compiler is permitted to violate the ABI for purely unit-internal things if it makes sense though, isn't it? Besides, in the case of the Linux kernel the ABI in question could be one of many. It could even be a new one which was added a couple of weeks ago, and which I had no _chance_ of considering. The rule stands -- empirical testing of what the compiler will do isn't usually the right answer. -- dwmw2 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
