Hi, I wonder if there is a pass in opt that removes unused function definitions. I'm working on a llvm based compiler backend and when I link the generated bc files with the runtime system and the standard library, all functions from the standard library are in the linked bc file, even unused ones. I've tried some different passes in "opt" but the definitions are still there. Regards Mattias
