Setting a function in a module to extern

JIT-Client for Shared Memory
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

[ORC JIT] -Resolving cross references in a multi-process scenario
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

JIT-Client for Shared Memory
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

Kinda like the KaldeiscopeJIT tutorials but in a guided way to ask questions and improve understanding about it.

Questions about moving from MCJIT to Orc JIT
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

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.

Setting a function in a module to extern
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

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

JIT crashing when compiling source code with Clang and -mretpoline flag
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

Attempting EuroLLVM2020 as a beginner
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

I could actually track down the cause of the problem: mainModue->getFunction("puts")->replaceAllUsesWith( llvm::ConstantExpr::getPointerCast( llvm::ConstantInt::get(llvm::IntegerType::get(context, 64), 0xF), mainModue->getFunction("puts")->getType() ) ); The problem is the line where I receive the type of the function "puts", it will crash the application

Why did "llvm.memcpy" changed when emitting an object file?
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

Questions after completed Kaleidoscope Chapter 1
Hi Bjoren, For question 1: As you mentioned, it is used to mangle to the symbol name and interning them, So ORC can find them at runtime in one of the JITDylibs. It would be helpful to know what you tried? (please attach code lines). For question 2: I guess you might be missing to link libraries that your program depend on, you can do that via setting up your dynamiclibrary search generator or
