similar to: [LLVMdev] Calling between modules

I'm trying to set up some automated testing, and I'd like to have multiple instances of ExecutionEngines, so that the state from the first test doesn't alter the second state. Right now I'm doing something along the lines of: Module *emptyModule = new Module("emptyModule"); ExecutionEngine executionEngine = ExecutionEngine::create(emptyModule);

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 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

Hello, I'm not sure what I am trying to do is possible. I'm trying to create two modules, and call a function in one module from another module. First, a reassurance that I'm not trying to do something completely off the wall would be nice as I don't see any tutorials that do this. Second, any help getting this to work would be wonderful. Thanks, Aaron In my code, you'll

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?

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

Hello, I am fairly new to LLVM development. Currently I am trying to treat LLVM modules almost like ".o" files in a "normal" development environment, and then calling functions in one module from another module. Is this possible? Basically, I want self contained chunks of code with dependencies on functions in other self contained chunks that get resolved at JIT time. I

Hi Kirill, Don't forget to add X86TargetMachine.obj (add to Additional Dependencies in Linker options, if you are using MSVS) otherwise LLVM will try and use Interpreter instead of JIT.

To fix it, I think you want to add a declaration telling the compiler to treat some_test_func()

Hello Everyone, I am trying to create two modules in LLVM, where first module contains the definition of a function, gcd in this example and another module contains a call to this function. My example is based on the following tutorial, with a few changes. http://llvm.org/releases/2.6/docs/tutorial/JITTutorial2.html When I execute the verifier pass on my modules, it complains that the

Hi, I am trying to generate LLVM code that calls a "native" function in the parent program (the program hosting the JIT). I think that I have figured out how to do this, but I get the following assertion failure when the LLVM code is executed: ../llvm/lib/Target/PowerPC/PPCJITInfo.cpp:206: failed assertion `ResultPtr >= -(1 << 23) && ResultPtr < (1 << 23)

Hi Gordon, I wrote a small example, but while running I get an error("Tied to execute an unknown external function"), where I am wrong? Thanks in advance. Kirill. int some_test_func( int ){ std::cout << "!!!!" << std::endl; return 8848; } int _tmain(int argc, _TCHAR* argv[]){ Module *M = new Module("test"); ExistingModuleProvider* MP = new

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:
