similar to: [LLVMdev] about pointer type

I feel a bit bad for always asking beginner questions here but I am having some difficulties with a runtime error with which I could use some help diagnosing. 1) I am getting the assertion failure main: Type.cpp:1309: static llvm::PointerType* llvm::PointerType::get(const llvm::Type*, unsigned int): Assertion `ValueType && "Can't get a pointer to <null> type!"'

I recently began hacking around with my first LLVM pass. The big picture is that I would like to insert function calls for each instruction type, and pass some parameters based on the instruction type. Then I will link the output to some C file that implements those functions. Things were going well until I started trying to make function calls with a pointer as a parameter. For example, I would

Hi,everyone. I'm writing a pass in which a CallInst to an external function will be inserted. The function is declared like this: void func(int a, unsigned chat *p); and in the Pass(a Function Pass ,and using the InstVistor template ), I wrote like this: void visitStoreInst(StoreInst &SI) { //Get the refference of the types Module *M =

Hi, For the following code const Type * Int32Type = IntegerType::getInt32Ty(getGlobalContext()); AllocaInst* newInst = new AllocaInst(Int32Type, 0, "flag", Bb); Bb->getInstList().push_back(newInst); It gives me the error " error: no matching constructor for initialization of 'llvm::AllocaInst' AllocaInst* newInst = new

I'm using LLVM 3.3 Release. From the Class Reference Page. CallInst has a member function : static CallInst * Create (Value *Func, ArrayRef< Value * > Args, const Twine &NameStr="", Instruction *InsertBefore=0) This is what I want to use! the default name is "" and I also use that .

The line comes up on a back trace using gdb. I think it's the right line (I have tried it on two separate machines one using Fedora 11 and g++ 4.4.x and the other Ubunto and g++ 4.3.3) and the situation is exceptionally odd since it only occurs when compiling my Runtime.cpp and doesnt happen when compiling other files. This is with LLVM 2.5. I did look at the Type.cpp code and it should be

ok.. So I am trying out what you have suggested. I have written the below code which basically tries to write the constant 10 to a file. myprint is a function pointer to a function which takes char * parameter and writes it to file. Value *Ten = ConstantInt::get(Type::Int32Ty, 10); const Type *VoidPtrTy = PointerType::getUnqual(Type::Int8Ty); AllocaInst *AI = new AllocaInst(Type::Int32Ty); Value

Hi, I need to insert new instruction into every basic block like x=1 or while loop I tried this code, but it doesn't work Type * Int32Type = IntegerType::getInt32Ty(getGlobalContext()); AllocaInst* newInst = new AllocaInst(Int32Type,"flag", Bb); Bb->getInstList().push_back(newInst); the error: void llvm::SymbolTableListTraits<llvm::Instruction,

Thank you for your help I tried Instruction* p=&( Bb->front()); Type * Int32Type = IntegerType::getInt32Ty(getGlobalContext()); AllocaInst* newInst = new AllocaInst(Int32Type,"flag", p); that works well but I need to store the value of the variable too. What's the method that could be used to store specific value?? On 30 July 2013 16:01, John Criswell

Hello, I am writing a JIT compiler for a subset of the Matlab language and as a part of my implementation, I would like to be able to pass a constant pointer to a native function I'm calling. Right now, this is what I do: llvm::Constant* constInt = llvm::ConstantInt::get(llvm::Type::Int64Ty, (int64)thePointer); llvm::Value* constPtr = llvm::ConstantExpr::getIntToPtr(constInt,

Hi, I'm Ryo Ota. I have two questions about `llvm::LLVMContext`. Q1) What is the difference between the following (A)`my_context` and (B)`global_context`? Do I have to create a LLVMContext by myself? Or use `getGlobalContext()`? Could you tell me what situation needs a LLVMContext which is created by myself such as (A)? (A) { llvm::LLVMContext my_context; // codes using only my_context (get

Hello everybody, my problem is, that I want to get an array of pointers to all local variables in a function. This array will be used for transfering these Variables to another execution engine. I've code which generates this array, and a pointer to the target field of the array. name = variables.fname + "_pointerArray"; Instruction* pointerArray = new
