C++ programs are likely to fail on IA64, as calls to setjmp are

The C++ front-end does not use IA64

There are a few ABI violations which will lead to problems when mixing LLVM

Defining vararg functions is not supported (but calling them is OK).

The Itanium backend is highly experimental, and has a number of known
