I believe this is the case with the IA-64 architecture. I don't have any experience writing compilers, but I would imagine that compile-time concurrency analysis (necessary for *decent* performance on IA-64) requires very clever optimizers. Come to think of it, I don't believe that plan9's comilers have been ported to IA-64 - is this the reason? --Joel ______________________________________________________ Due to economic circumstances, the light at the end of the tunnel has been turned off.
