llvm dev - Sep 2012 - [LLVMdev] Programmatically converting LLVM IR to native code

I am generating LLVM IR code and I would like to convert this IR code to native
code using the LLVM C++ API. This would be very similar to what's done in
the Kaleidoscope tutorial, but instead of relying on JIT compilation, I'd
like to emit native code -- the same native code that's produced by llc, for
instance.

I'm sure this is possible, but I wasn't able to find the resource I
need. Any help would be much appreciated.

Thanks in advance.

Have you looked at the source code for "llc" itself (in
tools/llc/llc.cpp)?  The API you're looking for is
TargetMachine::addPassesToEmitFile.

Thank you. I've started adapting this code.
