Creating and using LLVM bitcode libraries

Question

I have a C++ project that uses a C++ library that I also wrote. I\'m using clang++ 3.3 to build everything. Each file in the library is compiled as

clang++ -c -O         


        

Answer 1

EDIT: It is actually ar which makes it work.

Bit late but still might be relevant to someone, we use ar and ld.gold with LLVM plugin to link bitcode:

ar r --plugin /usr/lib64/llvm/LLVMgold.so library.a <files...>
ld.gold --plugin /usr/lib64/llvm/LLVMgold.so -plugin-opt emit-llvm  main.bc library.a

Of course the path to LLVMgold.so might be different. This way resulting .bc has just needed symbols.
