4) llvm.eh.typeid.for is not used.
5) Forced unwind behavior is not supported.
6) Very little if any error handling is given.
7) __attribute__((__aligned__)) is used.
8) The code uses parts from the llvm compiler-rt project and
the llvm Kaleidoscope example.
9) The code has not been ported or tested on WINDOWS.
