I want to insert new alloca Instruction after existing alloca Instruction in llvm pass so what attribute to be passed at last in following newallocaI = new AllocaInst(llvm::Type::getInt32PtrTy(context,0), //type 0, // ArraySize 8, // Alignment

I'm trying to create a GlobalVariable that is a ConstantArray. Id like each element to be a pointer to other things in the program(global variables, functions). So that they all have the same type Id like to make the elements void pointers. I think I am going about this wrong, heres how I am doing it: void writeArray(Module &M, GlobalVariable *shadow, Function *val,

I'm trying to create a GlobalVariable(that is a ConstantArray) in its own section. I want each element to be a pointer to a global thats already in the program(a variable or function). The follow code makes sense to me and compiles fine, but gives me the wrong output. When I look at the section in the ELF file it is larger than I expected and appears to be wrong. The contents of the array do

Hi all, I am new to LLVM, and I am learning how to use LLVM for profiling. I need to pass an array to an external method, and insert a call instruction to the method in the code. After reading a few source files, I've tried using GetElementPtrInst to pass an array, but it fails at llvm::GetElementPtrInst::hasAllZeroIndices() const + 0 std::vector<Value*> Args(1);
