We have some LLVM 3.4 based code that we are now trying to upgrade. There used to be the following API in LLVM 3.4 which is now gone:
Linker::LinkModules(dst, src, Linker::PreserveSource, &error);
The current function Linker::linkModules wants to take ownership of src and destroys it on return.
In our use case, src is a module containing a predefined set of inline functions. We link src with dst, optimize dst, emit object code for dst, destroy dst and then create a new dst module from our code generator and repeat this process. The src module is a constant throughout. What is the recommended way of doing something like this in current version of LLVM? Is there a way of copying only what is needed from src into dst and then updating all the call instructions in dst that refer to src functions?
Or do I just have to write something like this myself and not use linkModules?
