search for: existingmoduleproviders

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, I am expieriencing strange behaviour of llvm's optimization passes and I don't understand what I am doing wrong. Basically all I've done is extracting code for optimization of a llvm-function in a llvm-module and put it into a separate function for better readability. The original code looks like follows (and works as expected): ----------------------------- std::string

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, I'm experimenting with using LLVM to generate dynamic FFI bridges in VisualWorks Smalltalk. LLVM is an amazing thing! I'm going from dynamically generated assembler source to machine code, and I have that all working, copied from the llc tool and the JIT example. I have two questions: 1. What optimization passes, if any, should I run on the module before I pass it to the

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);

Hello, in the implementation of some analysis, I need to change the program and then invoke Mem2Reg pass. That pass, in turn, requires other analysis, so I must use PassManager. Here's the code I ended up with: bool runOnFunction(llvm::Function& m) { visit(m); ExistingModuleProvider mp(m.getParent());

First, I'm not sure if deleting the ExecutionEngine is all I need to clean-up... so I started with a minimal test just to check int main( int argc, char **argv ){ while( true ){ Module *M = new Module("M"); Function *F = cast<Function>(M->getOrInsertFunction("F", Type::Int32Ty, (Type*)0)); BasicBlock *BB = new

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()

I noticed that the ocaml compilation isn't using the .opt executables if they're available. We might gain a slight optimization in ocaml compile time by optionally using them with this patch. --- autoconf/configure.ac | 18 +++++ configure | 195 ++++++++++++++++++++++++++++++++++++++++++------ 2 files changed, 188 insertions(+), 25 deletions(-) -------------- next part

Hi Erick, Thanks, this looks good. Can you please resubmit this patch, and the others, as an attachment?
