similar to: LLVMLinkModules2() C-API question

Hello Duncan, Thank you for your reply. I did figure it out in the end. It was a linkage conflict between the modules. There were some global types that I was declaring in both modules. After removing them, linking worked perfectly. Still it's a mystery why I got no error string pointing me to the reason the linking failed in the first place.

Hello all, I am using llvm as a backend to a hobby language I am making. I have experimented with the C bindings since the project is written in C. I had no problems building a single lllvm module so far. I am not using a JIT compiler but at least at the moment am simply generating executables. The workflow I am using is to build a module with LLVMModuleCreateWithName() and populate it with the

I''m installing puppet modules from scratch on a new machine, using the code at https://hg.koumbit.net/module-puppet/ btw. The bootstrap script grabs a few base modules (to do dvcs checkouts) from http://reductivelabs.com/trac/puppet/wiki/CommonModules , uses the new modules to get the rest. However, the modules as checked out don''t bootstrap cleanly. The fix is simple, just

Hi all, I'm trying to use a function defined in one LLVM module from another module (in the JIT) but for some reason it's not working out. My sequence of activity is roughly like this: 1) Create moduleA 2) Create moduleB with "func()" 3) execEng = ExecutionEngine::create( new ExistingModuleProvider(moduleB)); 4) execute "func()" (this works fine)

Hi all, This is Michael and very happy to share my question here! My question is, is there a way to "extract" a function from Module A and write it into another Module B, and generate two new IR files? IRBuilder seems like a workable way but I have to create instructions one by one. I am new to LLVM so don't know whether it is doable, here is my experimental code:

Hi James, > This is interesting. I've just implemented dynamic loading of bitcode modules into lli for my project. I did this by hacking lli using the Linker class. Is ExecutionEngine::addGlobalMapping() preferred for this purpose? I'm not sure about the preferred way, but at least for the JIT, here is an email from Jeffrey concerning a previous thread. The issue in that thread was

Won't passing llvm::Function* around vs strings (function names), also work, at code generation time, without the need for a module A dec to module B impl. mapping?

Is there a preferred approach for an LLVM-based JIT-compiler to make calls from run-time generated functions in module A to bitcode-loaded functions in module B? A naive CallInst across the boundary fails verification. Calling it as an external function fails to resolve, even if both ModuleA and ModuleB are in the same ExecutionEngine. I can think of two ways around this: 1. Create a

The JIT tries to handle this in some cases (http://llvm.org/viewvc/llvm-project/llvm/trunk/lib/ExecutionEngine/ExecutionEngine.cpp?annotate=92771#l942), but doesn't handle it for functions. There aren't any tests, so I'm not surprised it's broken. The JIT would be simpler if we just dropped multiple-module support and asked people to link their modules together before trying to

Hey Lang, Thank you for your help and your patience – also for your answers in the “ORC JIT - Can modules independently managed with one LLJIT instance? + problems with ExecutionSession.lookup” mail. Both problems have the same origin so I keep writing about it here, to avoid duplication. My big problem is still handling cross references between modules with “our” name scheme. Since our old

Hi dear Users, I''ve been looking in internet and on the puppet wiki website but i am still confused about this. Lets say I have 2 Modules: A and B What I want to do is call a class on module A directly from module B. I know it is possible to call different classes within a module by using inheritance and using different .pp config files. But how I do not know how to do the

Greetings - Maybe I''m a bit slow, but I''ve been trying to understand how to use a module for the better part of a day and I''m not getting it. Here''s what I''ve done: Using puppet 0.23.2 1. Downloaded the shorewall module from David Schmitt''s git repo (Thanks David!!!!) and placed it in the directory /var/lib/puppet/modules (using the rpm

Hey Lang, > Do you mean that the object file is produced by another process and is being loaded into your JIT process for execution, or that you want your JIT to produce code for several different processes? These are different problems with different solutions. I'll wait until I understand your use case to answer further. In the current state we don’t have a JIT only an handcrafted object

Hey everyone, I felt this question is different from my other question - hope this is okay. So - I was playing around with the lookup function of the ExecutionSession and there are some things I don't understand. I have a .BC file with a function "?Sampler@@YAXXZ" referencing a value "?_Plansch_test@@3HA" that is not defined in that module itself. I first planed on not

Hi, I just put together a little mixin to provide pseudo-RESTful services in camping apps. Basically, it looks for a hidden _verb field in form posts, and sets the @method to the supplied value (e.g. put or delete - which browsers don''t support). This lets you define put and delete methods in your controllers. Groovy. Code: http://pastie.caboo.se/22613 Is there any permanent repo of
