Several people on this list have reported issues with the linker regarding a named StructType instance with the same name in two different modules being resolved into two StructTypes with different names due to StructType:: setName(…) collision behavior. Looking at BitcodeReader::ParseTypeTableBody(…), I don't see use of LLVMContextImpl::NamedStructTypes or of Module::getTypeByName(…). Nor do

Hi Andy, Here is the patch. it incorporates: 1) your latest patch to SVN. 2) mcjit-module-state-optimization.patch. 3) the PtrSet changes. Other than the OwnedModules implementation there were other differences between 1) and 2), especially in the Finalize* functions, so please review that I got the right code. I got bitten by subtle bugs arising from MCJIT inheriting from EE: First, MCJIT

Hi Yaron, Overall this looks great. There are a couple of remaining holes. Specifically, MCJIT inherits implementations of the FindFunctionNamed and runStaticConstructorsDestructors methods from ExecutionEngine which use the old Modules vector, so you'll need to override these in MCJIT. (The implementations are fairly trivial.) Beyond that I just have a couple of questions. First,

Hi Andy, I added the runStaticConstructorsDestructors and FindFunctionNamed functions. This also required making them virtual in EE.h. I'm not sure about FindFunctionNamed: In addition to searching finalized modules, should it search Added and Loaded modules? If it finds a Function in these, should it compile and finalize it before returning the Function* ? I modified the implementation

Agreed, the existing ownership seems sub-optimal. I wouldn't say broken, but subtle at least - looks like you get the choice to either manage the ownership of the Module object yourself, or let the context handle it (eg: currently it'd be valid to just do "{ LLVMContext C; new Module(C); new Module(C); }" - Modules end up owned by the context and cleaned up there). Might be hard

Just noticed that this problem only occurs from within RStudio (v1.1.414). Any ideas why?

In the most basic case, I'd imagine something like this: auto C = std::make_shared<LLVMContext>(); struct ModuleAndSharedContextDeleter { std::shared_ptr<LLVMContext> C; operator()(Module *M) { delete M; } /* ctor to init C */}; std::unique_ptr<Module, ModuleAndSharedDeleter> M(new Module(C.get()), ModuleAndSharedContextDeleter(C)); (or invert this and traffic in structs

The obvious guess would be that Rstudio is attempting something like redirecting output and getting itself confused. However, it is pretty clearly Their Problem, no?

I'm on llvm 3.8.1 and was wondering if there's a memory leak in the removeModule impl of mcjit. In the tutorial http://llvm.org/releases/3.8.1/docs/tutorial/LangImpl4.html a module is removed from the Jit by invoking removeModule. According to the tutorial: "Its API is very simple:: addModule adds an LLVM IR module to the JIT, making its functions available for execution;

Hi, Installing a source package on Windows using utils::install.packages() with quiet=TRUE fails, while it works with the default quiet = FALSE. The problem seems to be caused by the fact that when quiet = TRUE, stdout and stderr are set to FALSE when calling "R CMD INSTALL" with base::system2() here:

That means that you have to have used that key in an addModule call,

I'm trying to make a library in Xcode that links against LLVM. I used the STL C++ template in Xcode 4.5.2, added libLLVMCore.a and libLLVMSupport.a to the link binaries phase, and made this call in my code: llvm::LLVMContext& llvmCTX = llvm::getGlobalContext(); I get link errors against std::string and other STL classes: Undefined symbols for architecture x86_64:

Hi Kevin, Koffie, We will start migrating to ORC for next release, but for now, this release > invoke delete after remove right? MCJIT's removeModule method does not delete the module. You'll need to do that manually. OrcMCJITReplacement is a bug-for-bug compatible implementation of MCJIT using ORC components, so it does not free the memory either. Does this mean MCJIT is

Hello, I'm updating a legacy code using LLVM 2.5 where it has an iteration through a Module's TypeSymbolTable to process each StructType. In LLVM 3.4, TypeSymbolTable has been removed. I can only find the LLVMContextImpl instance of a Module's LLVMContext which has AnonStructTypes and NamedStructTypes two maps. However, LLVMContextImpl is an opaque class which cannot be directly

I'm trying to link two modules together using the C++ API, one that's a sort of library module and one that's being generated from the source language.
