[llvm-dev] Improve JIT C API

[Lang Hames via llvm-dev]

Hi Jauhien,

A few people have requested a C API for ORC. I don't think ORC's ready for
a stable C API, but I'm not opposed to providing C bindings that will
probably be reasonably stable in practice (though with no guarantees). I've
actually already knocked up some trivial prototype bindings for Hayden
Livingston that could serve as a base (see attached).

The next question is where unstable bindings should live. Juergen, Eric,
anyone else who wants to weigh in: I looked back over the C API thread, but
I don't think we settled on a home for this kind of thing. Any thoughts? I
could see either introducing a new include directory (something along the
lines of include/llvm/llvm-c-bindings) or a new c-bindings project on
llvm.org. The former would put all LLVM developers on the hook for
maintaining the bindings, the latter would leave maintenance to users of
the bindings project, and any volunteers. I prefer the second option: I
don't think core developers should be on the hook for maintaining unstable
bindings - that kind of special treatment should be reserved for the stable
API.

Cheers,
Lang.
