similar to: ORC JIT api, object files and stackmaps

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

Is it possible to inline functions compiled from C++ code into generated code that is fed, Module by Module, into the ORC JIT? I'd like to add a Module compiled from C++ code into the JIT and then as I add later modules, functions from the first module are inlined in the later ones. I already do this for file compilation/linking in my Common Lisp compiler “Clasp” (github.com/drmeister/clasp

Dear All I need to read the stackmap section at runtime of the inspected application. I've read the documentation of stackmap and found this paragraph: "A JIT compiler can easily access this section by providing its own memory manager via the LLVM C API LLVMCreateSimpleMCJITMemoryManager(). When creating the memory manager, the JIT provides a callback:

Hi all, hi Lang It's a little late to report issues for release_50, but I just found that thing while porting my JitFromScratch examples to 5.0. This is a really nifty detail, but (if I'm not mistaken) the function signature of RTDyldObjectLinkingLayer::NotifyLoadedFtor is incorrect: $ grep -h -r -A 1 "using NotifyLoadedFtor"

Hi All, The general initializer support patch has landed (see 85fb997659b plus follow up fixes). Some quick background: Until now ORC, like MCJIT, has handled static initializer discovery by searching for llvm.global_ctors and llvm.global_dtors arrays in the IR added to the JIT. This approach suffers from several drawbacks: 1) It provides no built-in support for other program representations:

Hi All, The initializer patch review at https://reviews.llvm.org/D74300 has been updated. The new version contains a MachOPlatform implementation that demonstrates how Platforms and ObjectLinkingLayer::Plugins can work together to implement platform specific initialization. In this case, the MachOPlatform installs a plugin that scans objects for __objc_classlist and __objc_selref sections and

Thanks! Currently using MCJIT. But migration to ORC is on my TODO list. - Paweł On Thu, May 12, 2016 at 8:30 PM Lang Hames <lhames at gmail.com> wrote: > Hi Pawel, > > Option (1) and (3) are very similar, but using custom resolution (option > 3) guarantees that JIT'd code can't accidentally end up depending on > functions in your JIT that you didn't mean to

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 ==

I tree to compile the LLVM ORC JIT examples. But I'm stuck in some problems I can't solve my own. First at all I compile with C++14 enabled with latest stable LLVM and clang, this means 4.0.1. I get the following error. Do I missed some specific compile option? Compilation looks like this here. |CompilingcontribJIT.cpp PWD:/home/ikuehl/projects-llvm/TurboLisp/domainEngineer

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 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.

Hi All, I've listed the current topics of interest below, along with some notes on each. We only have 30 minutes so we'll barely scratch the surface of these during the BoF itself. My main aims are for you to meet each other, identify potential areas of collaboration, identify things that I can do to unblock you, and get the ball rolling on some conversations that we can continue on the

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

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 I see in the tutorial), I get an LLVM error, "Program used external function

Hello LLVM-Mailing-List and hello Lang (I figured somebody would add you....so I did it directly. Sorry), I'm still playing around with the ORC JIT version which is available in LLVM 10. My goal is to get the address of every defined symbol in a module and an object file before the code is emitted. With the help of Lang I do this now with the lookup function of the Execution Session. Thank

Thanks so much! This seems to do the trick. I would have spun my wheels for a long time before discovering all of this, wow. Do I even want to know what additional chickens need to be sacrificed to get this to work on Windows? -- lg > On May 18, 2016, at 1:52 PM, Lang Hames <lhames at gmail.com> wrote: > > Hi Larry, > > You're basically there, but you're hitting

I upgraded my versions of llvm, clang and compiler-rt to the top-of-tree versions from last night (r180162, April 24). I recompiled debug versions of llvm, clang and my code. I then regenerated my test case and the results were the same - I can list lines of dwarf1.lsp in lldb but I can't set break-points or do anything else (what else should I be able to do?). The updated file that

Hi Larry, Thanks so much! This seems to do the trick. I would have spun my wheels for > a long time before discovering all of this, wow. No worries. :) I'll try to keep this in mind and make sure I address it in future Kaleidoscope tutorial chapters - these issues tripped me up the first time I encountered them too.

Hi, I wrote a compiler that generate IR code and run it on the JIT, and there randomly crashed due to "corrupted size vs. prev_size" depends on the IR code generated from the source code. Here's how I created the JIT: llvm::InitializeNativeTarget(); llvm::InitializeNativeTargetAsmPrinter(); llvm::InitializeNativeTargetAsmParser(); // create jit llvm::orc::ExecutionSession
