I'm a stubborn donkey. As lons as Marcel has not abandoned it, I'll use it. Regarding work/environment - the University has become about as stale, boring, risk averse, unimaginative as can be, with regard to computers, computing enviroment and general IT support attitudes. What is a poor user to do? I make a fuss. I complain to anybody and everybody. I'm trying to convice the director of IT and his varioius deputies, that they must recognise the diversity of computing needs in engineering. Windows desktop just doesn't do it for everybody. More to the point, I belive by using ia64, I contribute, in a small way, to the development of FreeBSD, e.g. sometimes ia64 code breakages indicate poor coding, and fixing code on ia64 actually fixes it on other arches too. With a massive help from linimon@ we managed last time to build over 15k ports on ia64 9 and 10. So things are not that bad. I would actually set only -march= because it should set mtune to the same value by default too. Moreover, I suspect mckinley is an alias for itanium2, as it was it's codename... Strangely, current gcc documentation for ia64 is missing references of march and mtune for ia64. http://gcc.gnu.org/onlinedocs/gcc-4.7.2/gcc/IA_002d64-Options.html There's no "-march", but for "-mtune" it says: -mtune=cpu-type Tune the instruction scheduling for a particular CPU, Valid values are itanium, itanium1, merced, itanium2, and mckinley. Thanks Anton
