...std::cout << "Hello World!" << std::endl; return 0; } So below is the break down of the steps that I do: First I compile this code to an instance of llvm::Module by using the logic borrowed from the lli tool. Once I have the Module instance I construct an instance of orc::LLLazyJIT (J), configure it (again closely following the logic in lli tool) to which I then add the module like this: // Add the main module. ExitOnErr(J->addLazyIRModule(orc::ThreadSafeModule(std::move(MainModule), TSCtx))); Finally the module is executed like this: // Run main....

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 == KV.second.getFlags() && "Resolving symbol with incorrect flags", file C:\work\github\llvm-9.0.0.src\lib\ExecutionEngine\Orc\Core.cpp, line 384 I am unsure what this assertion means and...

Hi Andres, Ok -- I've added some API for this in 438db0719681: You can get the string pool from the execution session with LLVMOrcExecutionSessionGetSymbolStringPool, then clear that with LLVMOrcSymbolStringPoolClearDeadEntries. -- Lang.

Hi Guys, Thanks for the interest in the xen hypervisor debugger, prev known as kdb. Btw. I''m gonna rename it to xdb for xen-debugger or hdb for hypervisor debugger. KDB is confusing people with linux kdb debugger and I often get emails where people think they need to apply linux kdb patch also... Anyways, attaching patch that is cleaned up of my debug code that I accidentally left in

When using ORC JIT, I'm having trouble with external function resolution (that is, of a function defined in the app, with C linkage). I add a declaration for the function to my IR, and when I use MCJIT, it finds it and all is well, But when I use ORC JIT (I *think* correctly, at least it closely matches what...

Right, but is there any known use case where Orc's flexibility allows something to be done that couldn't be with MCJIT, apart from lazy compilation?

Hi Lang, Thank you for your answer! This helped me again a lot!! Also that ResourceTracker is a really neat feature! Looking forward to it! :3 I changed the title cause… there is another issue I have (sorry about that…) I’m finally allowed to investigate the ORC JIT for integration into our system, which meant I got a few days to actually play around with it. However, another problem arise which breaks my concept. It is the never ending story of “cross references”. I have again two Modules, which are added to two different LLJIT instances, but they are ref...

I have a few questions about the new ORC JIT. I saw Lang Hames (hi!) excellent talk at the llvm-dev meeting a few weeks ago. The ORC JIT is undergoing some API changes and I'd like/need to take advantage of them. (1) How do I take ownership of the ObjectFile once the ORC JIT has created it? I'd like to take ownership of obje...

Hi, I’m wondering if it’s possible to debug code JIT’ed with the newer ORC JIT. The LLVM documentation has a page at llvm.org/docs/DebuggingJITedCode.html <http://llvm.org/docs/DebuggingJITedCode.html> showing an example of using gdb to debug MCJIT’ed code, but has no mention of ORC JIT. From searching around online I’ve gotten the impression that ORC JIT doe...
