Line 35:
It is also possible to create macros that implement exception-like control structures (especially useful if you use visual C++). You can implement exceptions with nothing more than setjmp and a linked list. However, you will need to create an exception class that all exceptions derive from, which implements some form of basic RTTI.
You can also implement the entire unwind library that matches the IA64 C++ Spec. Libc++ and Libc++abi provide great starting points for Layers 1 and 2. All thats needed is Layer 3 which provides the __Unwind_RaiseException logic which uses the "eh_frame" specs from LSB, DWARF4 spec, IA64 C++ spec and the System V spec. To see an example of how to do this, see [https://github.com/Bareflank/hypervisor/tree/master/bfunwind]
