...odule linking code goes roughly as follows: Linker linker(jittedModule); std::unique_ptr<llvm::Module> moduleToLink( getLazyIRFileModule(bcFileName, error, context)); linker.linkInModule(std::move(module), Linker::LinkOnlyNeeded | Linker::InternalizeLinkedSymbol); Our issue is with the Linker::LinkOnlyNeeded flag. Using it has a huge positive impact on link and compilation time :-). But, it causes the @llvm.global_ctors and @llvm.global_dtors references from the linked-in modules to be discarded :-(. AFAICT, the Linker code assumes ThinLTO when the LinkOn...
