similar to: Reuse llvm::ExecutionEngine

Heyho, I can only provide you with a screenshot for the first problem I noticed: [https://media.discordapp.net/attachments/534012750045642783/575369402195640321/unknown.png] This code will crash when calling "eeBuilder.create". But I also looked at what happens if I do reuse the llvm::ExecutionEngine. After the call to "finalizeObject" I use "removeModule" for the

Dear LLVM-Mailing list, I have a beginners question again - please don't be mad at me! I was playing around with llvm::Module instance and ended in iterating over all global values and functions. I then noticed the function "llvm.memcpy". As I understood, this is an intrinsic coming from the LLVM. So far so good! I then emitted an object file with the llvm::ExecutionEngine and

Heyho both Mailinglists, I'm not sure if I encountered a bug or if I'm doing something wrong. I compiled a "Hello World"-function with Clang to LLVM-IR code, while passing the "-mretpoline" flag. I tried jitting and calling that function with the KaleidoscopeJIT code, but when calling "lookup" for that function the application crashed. I also tried that file

But in my module this function already exist… I first want to delete it but without also deleting the calls to it… From: Boldizsar.Palotas at esa.int <Boldizsar.Palotas at esa.int> Sent: Donnerstag, 13.

Hello again, as mentioned in a different mail, I'm a beginner with the LLVM and writing a JIT-Client under Windows. In my llvm::Module I have a certain function - now I want to delete this function, but keep all the calls and references to it. I kind of want to set the function to an external function. Is this possible? Kind greetings Björn Als GmbH eingetragen im Handelsregister Bad

Hello everyone, I want to use the LLVM to write a JIT client, that works with shared memory. Currently I proceed as following: I wrote an own class that inherits "RTDyldMemoryManager". The functions "allocateCodeSection" and "allocateDataSection" are allocating local non-shared memory. I store there addresses in a std::vector. When the function

Hi Bjoern, Thanks for your patience. The good news is that there is a neater way to do this: ExecutionSession's lookup methods take a orc::SymbolState parameter which describes the state that symbols must reach before a query can return (See https://github.com/llvm/llvm-project/blob/d1a7bfca74365c6523e647fcedd84f8fa1972dd3/llvm/include/llvm/ExecutionEngine/Orc/Core.h#L1273).In your case you

Hello LLVM-World, currently I play around with a "llvm::Module" and an external function defined there "puts". Normally this function gets resolved in the JIT-Process but I wonder about two things: 1. Can I resolve the function already in this step? I used "replaceAllUsesWith" and passed a "llvm::ConstantInt" to the function. But this didn't

I received this request off-list: > I would really love seeing presentations or workshops about the JIT. Kinda like the KaldeiscopeJIT tutorials but in a guided way to ask questions and improve understanding about it. Especially for use under windows since this seems to be rather rare. -Hal On 11/26/19 10:49 AM, Hal Finkel wrote: If you have suggestions for content, sending that here is

Hi Bjoern, For single object files you can override the needsToReserveAllocationSpace method that is inherited from llvm::RuntimeDyld::MemoryManager (make it return true) and then implement the reserveAllocationSpace method to allocate memory for all sections up front. There is no easy way to do this for multiple object files. I think you would have to mimic the memory size calculations

Hello LLVM-Mailing-List and Lang, I have a very weird (or strict?) scenario and was curious if the ORC JIT can help me with it. Soo here it comes: I have currently a windows process ("Runtime") which does nothing but creating a shared memory with read, write and execute rights - and also writing some function addresses like from printf to it. Then I have two or more processes which

Hello again LLVM-Mailinglist, This time I have no technical question however... Personally I'm a big fan of the LLVM, the concept behind it - as far as I understood it - and your work in general. I use the LLVM to develop various JIT applications that load the LLVM bytecode files under Windows - my many many questions are usually about this subject. Still after a year I feel like being a

Hello LLVM-World, yeah... It's me again and still with the never ending (but cool) task of jitting BC files under windows. My setup is: LLVM 7.0.0, with the corresponding Clang, Visual Studio 2017 (Clang integrated via "vix" installer) and my target is also windows x64. I create BC files with clang-cl and have currently a new test code, which has a static variable inside a lambda

Heyho, Recently I tried out the ORCv2 JIT, especially the LLJIT. I gotta say, that I really like the new interface and the way you use it! However there is one thing I'm missing. I wrote a small bit code file, which should force having a global constructor. int wuff(); __declspec(noinline) int miau() { printf("Huhuhu"); return wuff(); } const int x = miau(); When I

Hey Stefan, The function looks like this: “; Function Attrs: nounwind declare i32 @puts(i8* nocapture readonly) local_unnamed_addr #2” I wondered if I can do the external symbol resolution without using the JIT and RuntimeDyld (for now). For me it sounds like something that could be possible… Kind greetings Björn From: Stefan Gränitz <stefan.graenitz at gmail.com> Sent: Dienstag, 15.

Nice! Let me try to answer some questions, Before that I have to mention this is ORC version 2 APIs and this is where the project is moving forward. JITDylib is the symbol table, basically for a JIT Symbol it have an associated materializers, (you can think of it like an entity that generate the address for that symbol), Example: compiler are materializers. So to add symbols to your own JIT you

Hello LLVM-Mailing list, in the past I was using the MCJIT (if I understand it correctly) to load IR modules, compile them and execute them. The speciality of this JIT was, that it was writing the compiled code into a shared memory - for a different process to execute them. For that task the JIT used a 'custom' memory manager, memory mapping and also resolved undefined references itself.
