llvm dev - Jan 2016 - C++ Code Invocation At Runtime

Hi llvm-dev

I am trying to read up some C++ code from a file into a string and then
compile it into some module/function and then invoke the same - all via
API.

Kind of JIT compilation if you will.

I have something similar from
http://thinkingeek.com/2016/01/17/tiny-gcc-front-part-6/ that's kind of
going this for C.

I am reasonably familiar with LLVM backend and its API, what's unclear is
how do I parse the front end C++ and map it to LLVM data structures. I am
sure someone has already solved this problem/done enough work for JIT. Any
help appreciated.

Thanks
  Arpan

We don't have that capability directly, although you can do that using the
Cling project (https://root.cern.ch/cling).
