...is the `IRUnitT` type? Or rather, how should I be creating the `PassManager`? Why does `EngineBuilder` require a `unique_ptr` for the `Module` now? After I create the builder I still need to reference the module, in particular to run the pass manager and look up functions to run. Same for `linker::linkInModule`. `createBasicAliasAnalyisPass` is gone. What is the replacement, or do I not need it anymore (I believe it was required to be run for other passes). `linkInModule` used to provide an error message output. Is there a way to get the error now that it is gone? -- edA-qa mort-ora-y http://mortor...

If I create a function in a module with: auto f = module->getOrInsertFunction( "eval_expr", ...) //create function Then later I link this with other modules: Linker link; link.LinkInModule( base_module ); link.LinkInModule( module ); Then I create an execution engine something like: auto ee = EngineBuilder( link.getModule() )...create(); If I attempt to run the function directly I get an error: ee->runFunction( f, args ); "LLVM ERROR: Program used external function '...

...cause IRMover tries to map the metadata that already mapped in the destination module, and it seems that this happens because two different IRMovers are used for the same destination (or composite) module. During LTO, an IRMover is created in thinLTOBackendTask function(tools/gold/gold-plugin.cpp). linkInModule function, which is called by thinLTOBackendTask, calls the ‘move’ function of this IRMover. The other IRMover is created when “TheLinker” is created in FunctionImporter::importFunctions (lib/Transforms/IPO/FunctionImport.cpp). thinLTOBackendTask invokes FunctionImporeter::importFunctions as well,...

...oaded. We are currently using the MCJIT API, but are planning to move to ORC very soon. Our LLVM module 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...

...ilation works fine, but at runtime, I encounter the following assertion: Assertion failed: FunctionType::isValidReturnType(getReturnType()) && !isa<OpaqueType>(getReturnType ()) && "invalid return type", file .\Function.cpp, line 164 This happens somewhere in "LinkInModule" when trying to link two loaded .bc-files (generated by llvm-g++). The weird point: The assertion fires because the comparison RetTy == Type::VoidTy in isValidReturnType() fails although the TypeID is 0, the printed type is "void" and the function actually *does* return void.

(5) The raw bitcode data and the 'testfn' are combined into a single module using LLVM's LinkinModule API, then fed into optimizer. What do you think is the proper fix for my use case? I can think of a few, but I don't think I have enough context to determine which is the most proper fix. (1) Remove all MetadataNode and attributes from the bitcode files.

The `Metadata`/`Value` split (PR21532) landed in r223802 -- at least, the C++ side of it. This was a rocky day, but I suppose that's what I get for failing to stage the change in smaller pieces. As of r223916 (lldb), I'm not aware of any remaining (in-tree) breakage, so if I've missed some problem in the sea of buildbot errors, please flag me down. I'll follow up soon with
