You might want to look at the atomic operations package that's included
here: http://www.hpl.hp.com/research/linux/qprof/download.php4 .
This isn't exactly a mature package, but I'm trying to get it there.
IA64 is relatively well-supported. And AFAIK, it's the only such package
that handles memory barriers explicitly and correctly (at least by
my definition of "correctly" :-) ).
Suggestions/bug reports/patches are welcome.
