search for: findfunctionnam

Hi Andy, I added the runStaticConstructorsDestructors and FindFunctionNamed functions. This also required making them virtual in EE.h. I'm not sure about FindFunctionNamed: In addition to searching finalized modules, should it search Added and Loaded modules? If it finds a Function in these, should it compile and finalize it before returning the Function* ? I modif...

Hi Yaron, Overall this looks great. There are a couple of remaining holes. Specifically, MCJIT inherits implementations of the FindFunctionNamed and runStaticConstructorsDestructors methods from ExecutionEngine which use the old Modules vector, so you'll need to override these in MCJIT. (The implementations are fairly trivial.) Beyond that I just have a couple of questions. First, OwningModuleContainer::hasModuleBeenAdded seems wro...

Hi Andy, Here is the patch. it incorporates: 1) your latest patch to SVN. 2) mcjit-module-state-optimization.patch. 3) the PtrSet changes. Other than the OwnedModules implementation there were other differences between 1) and 2), especially in the Finalize* functions, so please review that I got the right code. I got bitten by subtle bugs arising from MCJIT inheriting from EE: First, MCJIT

...l the functions will be called. Is there a way to compile all the functions immediately (I guess this would be slightly more efficient)? 3. The compiled code needs to call functions in the host application. Dynamic linking is not an option (Windows). I'm now using the ExecutionEngine's FindFunctionNamed and addGlobalMapping method to bind declared external functions in the compiled code to host functions. Is this the best way to do it? Thanks! Alain

Hi, Could you share how you compile IR and which version of JIT you use (Orc, MCJIT)? Could it be that you are using interpreter instead of actual JIT? Cheers, Alex. > On 5.

I'm having issues of my compiler, and JIT execution, of LLVM IR being rather slow. It's accounting for the vast majority of my full compilation time.  I'm trying to figure out why this is happening, since it's becoming an impediment.  (Note: by slow I mean about 3s of time for only about 2K of my front-end code, 65K lines of LLVM-IR) Using valgrind I see some functions which seem
