C++ Code Invocation At Runtime

Project Infrastructure LLVM Dev List Archives

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 (Cling - ROOT).
