Make LLVM inline a function from a library

Question

I am trying to make LLVM inline a function from a library. I have LLVM bitcode files (manually generated) that I linked together with llvm-link, I also have a library (written in C) compiled into bitcode by clang and archived with llvm-ar. I manage to link everything together and to execute but i can't manage to get LLVM to inline a function from the library. Any clue about how this should be done?

Answer 1

After you link the bitcode files together with the library, do you run an Internalize pass on the linked bitcode? The internalize pass makes all functions (besides main()) static an tells optimizer/code generator that the functions can be safely inlined without keeping a copy available for some (non-existent) external reference.

I manually link my bitcode files and bitcode libraries together using code borrowed from llvm-ld and I do the internalize pass, but I'm not sure if llvm-link does the internalize pass or not.
