Please apply the attached (small) patch on top of it in the gcc directory. Worth noting, this front-end only works

I have llvm code that uses llvm::Type::UIntTy, llvm::Type::IntTy, and llvm::Type::SByteTy, but these are now removed. What should I use for their replacement. If I need to specify a size for IntTy and UIntTy, I want them to be the same size that an integer would be in C on the platform on which I'm compiling. So, if I need the sizes is their a way to fetch the size that an integer

Hi folks, I was just wondering if someone would be willing to tell me the best way to make a new structure type in LLVM and get it inserted as a valid type into a particular Module instance? I've done the following: vector<const Type*> types; types.push_back(Type::UIntTy); types.push_back(Type::UIntTy); structType = StructType::get(types); But

Hi Misha, Thanks for your answer I was doing this: ======================== BasicBlock *BBlock = new BasicBlock("entry", MyFunc); ... Value *Zero = ConstantSInt::get(Type::IntTy, 0); Value *UZero = ConstantUInt::get(Type::UIntTy, 0); MallocInst* mi = new MallocInst( STyStru ); mi->setName("tmp.0"); BBlock->getInstList().push_back( mi );

I'm trying to pass an array pointer to my run-time generated module, and after a long time of searching for the answer, the only thing I got was a headache. Basically I have a few arrays (few megabytes which will sometimes be accessed as 8 / 16 / 32 / 64 bit binary / fp values), that will be modified by both the generated module, and my main c program, so I would like to put those into global

This question is similar to Ryan Lefever's post on May 1, 2006 about printf declaration. In my case, I want to insert fprintf(stderr, ...) calls. I'm new to LLVM, and I don't know what's the recipe for putting together the arguments. Can someone give me basic instructions or point me in the direction on what to do? I can't find any more documentation on this. Thanks!

Ok, I think I figured it out. I talked to someone, and we figured out that when I make a call to printf with a constant string, I need to make a global variable and use getElementPtr to reference it. The modified call for accessing the printf is: /* m is Module*, f is Function*, i is Instruction* */ Constant* constStr = ConstantArray::get("test\n"); GlobalVariable* gv =

I am writing a pass where I need to make a function deceleration for printf. Below is the code I'm trying to use. ----- bool MyPass::runOnModule(Module &m) { vector<const Type*> args; args.push_back(PointerType::get(Type::SByteTy)); Function* f = m.getOrInsertFunction("printf", FunctionType::get(Type::IntTy, args, true)); ----- When I insert a call

Hi all, I was trying to implement an obfuscation tool for C-code on the basis of LLVM. I got a prototype of the simple obfuscation transformation which converting control flow graph to something like a state machine. I am not sure I will have time to work on extending further this tool with new transformations like opaque predicates and decided to put here source code I have by now with hope

I'm trying to insert a call to fprintf(stderr, ...). I've looked at the emitted assembly from llvm-gcc, and it consists of a LoadInst (of stderr) and CallInst. It looks like this: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %tmp.1 = load %struct._IO_FILE** %stderr ; ty=%struct._IO_FILE* %tmp.0 = call int (%struct._IO_FILE*, sbyte*, ...)* %fprintf(%struct._IO_FILE* %tmp.1, sbyte*

Right now I am trying to capture the function name and the number of arguments , so this following is the pass I wrote . ------------------------------------------------------------- struct pass06a : public ModulePass { virtual bool runOnModule(Module &M) { std::vector<const Type*> pList; pList.push_back( PointerType::get(Type::SByteTy) ); pList.push_back(

HI , I understand that the standard C library functions are executed using the native library of the host machine. ( for example when we execute a bytecode to extract the profile info ) Is it possible to extract for each standard library function that is executed , the arguments that the function is called with. For example if printf ("%d", some_int ) when called during runtime

Hi, Thank Brian Gaeke so much. Following TraceBasicBlocks.cpp, I modified the code as below and could insert instruction or function I need into anywhere in Module. But it works well without BB->getInstList().push_back(InstrCall), and if I add the BB->getInstList().push_back() following new CallInst(), I got error information when runing opt. What is the reason for it? And is it necessary

Hopefully I've understood the llvm source
