Hi, I updated my project to LLVM 10.0 today and I am getting JIT symbol resolution errors. I could not find any example or updated tutorial or documentation that describes the new api - as all documentation seems out of date. I paste below some code snippets that show what I am doing: /* global syms is a array mapping names to function addresses */

Hi All, There was only one interesting ORC-specific commit this week: A new example showing how to initialize and de-initialize JITDylibs has been added in llvm/examples/OrcV2Examples/LLJITWithInitializers. The Extensible RTTI system (https://reviews.llvm.org/D39111) that I posted a while back has landed. While this is not ORC specific, I expect it to be used in upcoming patches to allow ORC

Hey Lang, I would be really happy to only have one LLJIT instance and using multiple JITDylibs. However… it seems like that I don’t know enough to use them. So I wonder… 1. When I add Module A to JITDylib A and Module B to JITDylib B – where will those look for undefined symbols? Will Module A for example: will it only search itself and the MainDylib? Or would it also search in JITDylib B?

Hi Emmanuel, Thank you very much for these! I will check them out today and see what's going on. Regards, Lang.

Hello Lang, Good work! That was very quick ;-) > I will file a bug tomorrow to add COMDAT support to ORC. I won't have time to work on this feature any time soon, but I will try to provide a sketch of the solution in the bug report in case you or anyone else is interested in taking up the challenge. :) => I suspect this could be an issue that could get in my way more significantly

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

I write a small function and test it under clang and gcc, filet test.c: double X[100]; double Y[100]; double DA = 0.3; int f() { int i; for (i = 0; i < 100; i++) Y[i] = Y[i] - DA * X[i]; return 0; } clang -S -O3 -o test.s test.c -march=native -ccc-echo result: "D:/work/trunk/bin/Release/clang.exe" -cc1 -triple i686-pc-win32 -S -disable-fr e -disable-llvm-verifier

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 Bjoern, CC'ing Lang hames For questions, 1. In short yes, you can replace the memory manager, default one provided is section memory manager. 2. If you mean by " address of already compiled code", yes you can do that. Like this JITDylib.define(absoluteSymbols, ( Your_own_symbol , JITTargetAddress(Address of function))), now ORC can resolve all the references to Your_own_symbol

Hi folks, Rather by accident than on purpose I looked at the release notes and found the following: http://releases.llvm.org/8.0.0/docs/ReleaseNotes.html#changes-to-the-jit-apis TL;DR: Orc v1 is deprecated and will be removed in the next release. I have several questions in this regard: 1. Is there a migration guide I can use to update my code to the new version? 2. Is there any development

Hello, I am trying to run this basic C++ hello-world code in my iOS app that has LLVM libraries linked in (the app runs on the actual device - iPad Pro, iOS 13.4.1). #include <iostream> int main (int argh, char *argv[]) { 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

I was just reading the blog post -- very cool! Regarding Globals construction & destruction: There definitely has been a lot of churn in that area. There will probably be more before LLVM 11 is released, but I can see light at the end of the tunnel. I think the Right Way to run initializers in a JITDylib is to treat it as equivalent to a dlopen operation (with extra allowances for the fact

For example, the illustrate part says "ES.getMainJITDylib().setGenerator" while the full code list says "ES.getMainJITDylib().addGenerator", I guess the API is changed, the tutorial part is up to date while the full code list leaves to the old version.

Hi Dave, Yep. This is JITLink specific, so we could only have observed it on MachO x86-64 or arm64 until recently. It takes a little bit of poking to get IR to produce a zero-lengh section on MachO, but not much. Jared Wyles recently contributed an initial JITLink ELF implementation, so the fix seems timely -- we might have been about to see more of it. -- Lang. On Fri, Jun 19, 2020 at 4:02 PM

Hi all, i use Samba 3.5.6 in ads mode (Windows 2008R2) with ldap idmap backend. Servers run Centos 4 and 5. I can't cope with next issue for long time. On all servers in domain winbind constantly tries to create mapping for <SID>-513 and fails because of already existing entry. It just wastes gid range. Note that <SID> is not SID of main domain but another which name equal to
