[cfe-dev] How to use clang and llvm for JIT, preferably via the C API

[Joel Andersson via cfe-dev]

Hi!

I'm trying to add JIT support to our software for mathematical optimization
(http://casadi.org), but it's proving difficult. Since we already support
generation of C code, the natural approach is to generate C code (either as
temporary files or as strings) and parse this code using clang. Although
we've managed to implement a proof-of-concept, I'm struggling to implement
something more maintainable.

In particular, I'd like to use the C API (libclang), but I don't see how
this can be combined with JIT. If I want to do clang+JIT, am I forced to
use the (unstable) C++ API?

Here is a stackoverflow post I posted on the subject (without luck):

Best regards,
Joel

P.S. I'm also struggling to set up our (CMake-based) build system so that
it works with multiple llvm versions and multiple platforms. The
"llvm-config" doesn't appear to have anything clang-related. But I guess
that's a separate issue.
