llvm dev - Jan 2008 - [LLVMdev] Calling between modules

Hello,
I am fairly new to LLVM development.  Currently I am trying to treat LLVM
modules almost like ".o" files in a "normal" development
environment, and
then calling functions in one module from another module.  Is this possible?

Basically, I want self contained chunks of code with dependencies on
functions in other self contained chunks that get resolved at JIT time.  I
figured since the ExecutionEngine has an "addModuleProvider" function,
this
sort of behavior is supported.  If not, what is addModuleProvider's intended
use?

When I can get LLVM to do what I want, it is truly incredible!  Thanks for a
great project!

Yes! In fact, that's close to what modules are in LLVM. If you want  
to call a function outside of a .o file, then you have an external  
declaration of that function in the module, and then call it like  
normal. You link the .o files like normal to create the final  
executable.
