It seems that a client application needs to call InitializeNativeTarget or LLVMInitializeNativeTarget before doing any JITting. Unfortunately, LLVMInitializeNativeTarget is defined static inline and does not appear in the .a files; thus a client not written in C or C++ trying to JIT cannot link to the library and call LLVMInitializeNativeTarget that way. It can call...

'My' current LLVM code (see https://github.com/opencor/opencor/blob/master/src/plugins/simulation/CoreSi mulation/src/coresimulationplugin.cpp) is a shameless copy/paste of the HowToUseJIT example (in the examples folder).

Hello All, I'm building an F# binding for LLVM and it seems to be working for the parts of Core and BitWriter that I've tested but I've hit problems with Target/ExecutionEngine. The following test code works with the initializeNativeTarget line commented out like so: <https://github.com/keithshep/llvm-fs/blob/b7050b841108dc703e58563a4cff8845603c950d/test/simpletest2.fs> ... but if I uncomment the initializeNativeTarget line I get the following error from mono: Unhandled Exception: System.EntryPointNotFoundException: LLVMInit...

I *just* changed this. :) For JIT applications, please include llvm/Target/TargetSelect.h and call the llvm::InitializeNativeTarget() function before creating an EE. -Chris

Hi, Why are there so many undocumented (and as I far I can see) unnecessary API changes? Recently there has been: 1. For JIT applications, please include llvm/Target/TargetSelect.h and call the llvm::InitializeNativeTarget() function before creating an EE. 2. The major CHANGE is: the JIT will no longer be safe for executing threaded applications without first invoking llvm_start_multithreaded(). Please begin to update your client applications now if this affects you, as I will be throwing the switch in SVN soon...

Hi, guys. Have a strange problem with LLVM in my project ( https://github.com/ababo/AntOS). Cannot instantiate JIT execution engine (NULL returns; message: Interpreter has not been linked in.). As you can see from the code I call InitializeNativeTarget. Also I tried to directly include the "llvm/ExecutionEngine/JIT.h" header, but with no success. I link with `llvm-config --ldflags --libs core jit native`, so there's no problem here. Can you suggest me anything? Thanks. -------------- next part -------------- An HTML attachment was s...

Hi, I'm on Linux and trying to link an application that makes use of LLVM's JIT execution engine statically. Setup: (1) LLVM libs are compiled as static libraries. (2) Called InitializeNativeTarget(). (3) Included llvm/ExecutionEngine/JIT.h. It works if I build and link regularly. However, if I add -static when linking, the execution engine fails to initialize. Does anyone know why? LLVM libs are already archives. Is that supported at all? Thanks & ciao, Mario

Can someone pease tell me what I am doing wrong? Im trying to register an external function with the JIT, so can call functions in my music application. Here my function int Execute(llvm::Module *Mod, char * const *envp) { llvm::InitializeNativeTarget(); std::string Error; llvm::OwningPtr<llvm::ExecutionEngine> EE( llvm::ExecutionEngine::createJIT(Mod, &Error)); if (!EE) { llvm::errs() << "unable to make execution engine: " << Error << "\n"; return 255; } // code I have added -------...

hi, im creating a music application(image below). At the moment im using tcc compiler but im moving across to clang because of the improved compiler warnings. Can anyone please explain and show code so I can use clang's JIT to call functions in my application? Thanks. http://old.nabble.com/file/p29449300/51709341.jpeg -- View this message in context:

I assume that I'm just not doing something necessary for initialization, but I'm not sure what it would be--I am calling all of: llvm::InitializeNativeTarget(); llvm::InitializeAllTargetMCs(); LLVMLinkInMCJIT(); LLVMLinkInJIT(); and the module I'm trying to load does have a reasonable target: target triple = "x86_64-apple-darwin11.0.0" I've attached a short test case that has the sequence of calls that I'm making and...
