Hi On Windows 10 when using a debug build of LLVM 10, I get this assertion failure: Assertion failed: (KV.second.getFlags() & ~WeakFlags) == (I->second & ~WeakFlags) && "Resolving symbol with incorrect flags", file C:\work\github\llvm-10.0.0.src\lib\ExecutionEngine\Orc\Core.cpp, line 450 The same failure occurred in LLVM 9 too: Assertion failed: I->second ==

Hi There, I am currently exploring C++ JIT-compilation for a project where this would be very useful. I started with the code from the lli tool which uses OrcLazyJIT and changed it, such that the module is being compiled from c++ source in memory and OrcLazyJIT is used exclusively. Now since I am on windows, I found that my application is crashing when trying to run the main function from the

Hi all, Attention: Lang Hames I am developing the nGraph MLIR<https://github.com/NervanaSystems/ngraph/tree/master/src/contrib/mlir> implementation and hitting the following assert while running nGraph unit tests: assert(ObjectBufferMap.find(K) == ObjectBufferMap.end() && "Second attempt to perform debug registration."); Here is a

Hi David, This is really cool. I'd love to get this in-tree. There are two ways we could go about this: (1) Make the OrcArchitecture interface ABI-aware so that it can choose the right resolver code, or (2) Replace the OrcArchitecture classes with OrcABI classes. I.e. We'd just a rename OrcX86_64 -> Orc_X86_64_SysV (and rename I386 & AArch64 similarly) , then we add your code as

Hi Adam, Calls to the listeners should be protected by the RTDyldLayerMutex. Could you apply the attached patch and share the debugging output from one of the failing runs? Regards, Lang.

Referring to the log messages from my previous mail… I confused myself (and probably others) by reading the “Adding MemMgr 0x55555959f440“ message as “Registering MemMgr 0x55555959f440”. Thus the address mismatch made no sense. How could we be registering a `MemMgr` address/key that does not match once we arrive in `notifyObjectLoaded` method? Answer: Because the registrations is NOT coming

Hi Lang, LoadedObjectInfo::getSectionLoadAddress takes StringRef as an arg. That breaks if the object file has multiple sections with the same name. I made a change to add an overload that takes a SectionRef&. Can you please take a look? https://github.com/erozenfeld/llvm/commit/65f635e426bdc8e80a29ed370a78f0c0a282f265 Thanks, Eugene -------------- next part -------------- An HTML

Hi Christian Your use case seems to have similar requirements as remote JITing in ORC. So far I haven't used that part myself and I am sure Lang can tell you much more about it. However, this comment on the RemoteObjectClientLayer class sounds promising for your questions (1) and (2): /// Sending relocatable objects to the server (rather than fully relocated /// bits) allows JIT'd code

Hi, We are making the move from legacy JIT (llvm-3.5.x) to ORC JIT and I am looking to recompile (and re-link) functions at runtime for an ARM platform (Odroid XU3) . I looked at OrcLazyJIT.cpp as a starting point. However, after going through the code, it appears that the createCompileCallbackMgr (llvm-3.8.0) / createLocalCompileCallbackManager (llvm-git) do not support an ARM triple yet.

No real reason, just wanted to get an informal opinion first.

Having something like this available in tree would definitely be useful. For simplicity, why don't we start with support for the second style? This is the long term useful one and would be a good starting point for getting the code in tree. Can you give a pointer to the patch so that I can assess the rough complexity? If it's simple enough, I'd be happy to help get it reviewed

Hi all, I'm trying to add pre-compiled object cache to my run-time. I've implemented the object cache as follow: class EngineObjectCache : public llvm::ObjectCache { private: std::unordered_map<std::string, std::unique_ptr<llvm::MemoryBuffer>> CachedObjs; public: virtual void notifyObjectCompiled(const llvm::Module *M, llvm::MemoryBufferRef Obj) { auto id =

When we were using MCJIT, I could do this: // Attach the event listener Context.EE->RegisterJITEventListener( LLILCJitEventListener::createLLILCJitEventListener( new LLILCJitEventWrapper(&Context))); The event listeners listened for when an object is emitted (NotifyObjectEmitted), and that’s when we’d go through and extract debug info from the ObjectFile. Now, I imagine

Hi, Not sure whether this matches your use case, but the Orc-based JIT used in LLI appears to be using `llvm::orc::LocalCXXRuntimeOverrides` (http://llvm.org/doxygen/classllvm_1_1orc_1_1LocalCXXRuntimeOverrides.html) to override `__cxa_atexit`: https://github.com/llvm-mirror/llvm/blob/release_50/tools/lli/OrcLazyJIT.h#L74
