similar to: [LLVMdev] Forcing the Interpreter segfaults

In my case, I am working on a posix regular expression library that uses LLVM to execute a regular expression. Each regular expression is a very small sets of code and is faster to interpret than to JIT then execute. I wanted to JIT only when the regular expression is executed more than 20 times. The benchmarks I have run show that my library is amzingly fast to execute a regular expression

Hi everyone ! I am very new to LLVM and intent to use it in a research project. I have a problem with the interpreter: I have a simple compiler that generates LLVM bitcode, JIT it and execute it, and it works very well. Now I would like to execute it using the interpreter. And I get a segfault. Here is the code : // This code JIT the function and executes it llvm::InitializeNativeTarget();

Hi Salomon, please don't forget to reply to the list too (I've CC'd the list). > I don't think my code is doing anything worng... No, it looks fine to me, and the interpreter certainly supports this. That suggests that the value of %str is not being transmitted to the function right. If it is getting the wrong pointer value, that would explain why it barfs. Ciao, Duncan.

You need a pointer-to-function type, but FunctionType just gives you a function type. Use PointerType::getUnqual(FunctionType::get(...)). Or TypeBuilder<char (*func)(void*), false>::get(context) from Support/TypeBuilder.h.

Hi all. I would like to declare a function that takes a function pointer as an argument. In C, it would be : void execute(char (*func)(void*), void *param) So, in my compiler, I have : std::vector<const Type *> cbFPtrArgs(1, Type::getInt8PtrTy(C)); FunctionType * cbFPtrTy = FunctionType::get(Type::getInt8Ty(C), cbFPtrArgs, false); Function * func =

Hello R-users, I have been trying to fit what I think is a simple mixed-effects model using lmer (from lme4), but I've run into some difficulty that I have not been able to resolve using the existing archives or Pinheiro and Bates (2000). I am measuring populations (of birds) which change with time at a number of different sites. These sites are grouped into regions. Sites are not measured

Hi, I'm trying to work out the correct way of JITing multiple modules. My original approach was to create a new ExecutionEngine for each Module, however this generates an assert failure. If I create a new ModuleProvider for each new Module and then add this to a single ExecutionEngine then I have a problem with static constructors not being run. With a single module, I can call
