Hi LLVMers, the example attached I have used to prove that JIT and some visible optimizations are really invoked. Proved OK. I got 30% speed-up in comparison to gcc 3.3.3 on my Athlon XP 1500. Nice. P.S. guys, no fears, I don't plan to flood the cvs repository with my "brilliant" examples ;) --- Valery A.Khamenya -------------- next part -------------- An

The type you want is: let sp =

So my Fib program is segfaulting and I'm not sure why. I think it might be because my declaration and use of sprintf is wrong. I notice llvm-gcc produces declarations containing "..." like: declare int %printf(sbyte*, ...) but I'm not sure how to do this so I've used: let sprintf = declare_function "sprintf" (function_type (pointer_type

Hi, I don't think the code you pasted can be the correct code, where does FibF come from? Anyway, the problem is that you're calling the FibF from Module A, however you defined it for Module B. You need to insert the FibF function into the Module that you're running. To do this override "virtual bool doInitialization(Module &M);" and insert FibF into M...

Here's my translation of the Fibonacci example into OCaml: open Printf open Llvm let build_fib m = let fibf = define_function "fib" (function_type i32_type [| i32_type |]) m in let bb = builder_at_end (entry_block fibf) in let one = const_int i32_type 1 and two = const_int i32_type 2 in let argx = param fibf 0 in set_value_name "AnArg" argx; let retbb = append_...

...ArgT, /*not vararg*/false); // Now create the fib function entry and // insert this entry into module M // (By passing a module as the last parameter to the Functionconstructor, // it automatically gets appended to the Module.) FibF = new Function(FibT, Function::ExternalLinkage, // maybe too much "fib", M); You can do this same thing with code like this: Function *FibF = M->getOrInsertFunction("fib", Type::IntTy, Type::IntTy, 0); Thanks! I really lik...

...t;. 2, Use the "insertBefore"API to insert the CallInst into the right position. My problem is about the step 1. How can I get the handle of the .bc file (Probably is a Module*)? so I can declare the extern function like // insert the " i32 @fib(i32 )" to the module M Function *FibF = cast<Function>(M->getOrInsertFunction("fib", Type::getInt32Ty(Context), Type::getInt32Ty(Context), (Type *)0)); How can I get the "M" of the .bc file?????? Any help~ --...

...mply deleting the execution engine instance in the fibonacci code and looping all the main code give me memory leaks. Can anybody confirm this? - Conserving the module, the execution engine and the module provider, but releasing the fibonacci function with: EE->freeMachineCodeForFunction(FibF); FibF->eraseFromParent(); and recreating the function from scratch leaks even more. Idem, someone can confirm this? Thanks in advance. Paolo Invernizzi
