[LLVMdev] Dynamically loading native code generated from LLVM IR

Hi Armin,

If you use dlopen or getPermanentLibrary to open those libraries then
the JIT's relocation processing will normally find the referenced
symbols correctly. (With caveats for remote targets and so on, of
course).

That solution assumes your external libraries are shared, of course.
If they're static then I'm not sure there's a solution at present.
There's no reason in principle why the JIT couldn't load prebuilt
objects or archives, but it doesn't even seem to support multiple LLVM
modules at the moment, so infrastructure is probably missing.

Tim.
