However, in general what Itanium does is not a win since in
practice most functions do not need local storage (even if
written in a language richer than C!).
That's not true. .dlls are the primary use case for this. If a .dll
has it's own local memory and local allocator, this is a big,

I know most everyone here hates the Itanium, but it is in some pretty large and
fast systems, and it's on the Top500 list.
So out of curiosity, has anyone looked at putting together a compiler for
Itanium, or otherwise looked at a Plan 9 port?
