On the (now somewhat old) 2.6.18 kernel I use it is an option under "Processor type and features" called "Use register arguments", but yeah it isn't an option anymore in new kernels. As for your argument that it isn't a good idea, well most of the time the arguments you want to pass to a function are already values you were just working with to get them ready for the function, so quite likely they are already in the registers you are worried about having to clear first. Add to that the ability of modern x86 CPUs to use rename registers to fake stack accesses in some cases and the clearing of the registers become pretty much a non issue, at least that's my understanding of how things work. -- Len Sorensen -- 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/
