As an aside: unless they've changed it recently, on IA64 icc provides
only intrinsics and doesn't allow inline assembly at all. Granted
very few people are going to _want_ to write IA64 assembly anyway, so
it's not that surprising. A downside is that since they don't provide
intrinsics for every possible instruction and hint combination, there
are some obscure but potentially useful instructions that it can't
generate.
