I've been reading about LLVM and clang and I understand that the LLVM framework generates object files for the target machine and the system linker (ld, for linux) does the dynamic linking.
But I don't understand how things work when JIT compilation takes place. Is the system linker still invoked in this case? I see that there is a RuntimeDyld.cpp file. Is it to link between different bitcode files being JIT compiled, or does it link to other shared libraries that are loaded dynamically?
