LLVMers, The long awaited conclusion of bug 122 (VMCore cleanups) is very near. I have just committed all the changes to rid LLVM of the ConstantPointerRef abomination. This class no longer exists. Just use GlobalValue, GlobalVariable or Function directly. The changes pass 100% of Feature and Regression tests. Two minor discrepancies against the Programs tests were detected but these were

Hi, I have this call instruction to printf inserted which is causing an assertion failure. Any pointers to where I am wrong : Code Dump : Function *printFn=M.getNamedFunction(std::string("printf")); Constant *str=ConstantArray::get("Value : %d\n"); std::vector<Value *> Args(2); std::vector<Constant *> GEPIndices(2);

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 , I am using LLVM for my Post Graduate course project on Optimization. I am trying to do some insrtumentation to the bytecode.I 've been going through your Instrumentation code for the past few days in /llvm/lib/Transforms/Instrumentation folder and finally found two ways of instrumentation : 1) injecting LLVM bytecode instructions 2) calling an external C function. I am trying both and

Hi, I want to access an array in my instrumentation code. For example: GlobalVariable: int *counter; //counter the number of load/store operations in run-time int *counterArray; //record the load/store addresses //increase the counter if a load/store is performed std::vector<Constant *>index(2); index[0] = Constant::getNullvalue(Type:getInt32Ty(Context)); index[1] =

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 =

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, Sorry for bothering you guys again. I got problem when I am trying to recover the Global Variable Initial value. What I did is like the following ConstantArray *Cstr = dyn_cast<ConstantArray>(gI->getInitializer()); // the above instruction enable me to get the content of initial string of global variable, like char a[10] ="test global"; And then I make some change for

Constant *strcon==ConstantArray::get("Value : %d\n"); Sorry Typo.

Thank you, Duncan. I rewrote the code, please help check why it still does not work: //declare global variable const Type *IntTy = Type::getInt32Ty(M.getContext()); const Type *ATyC = ArrayType::get(Type::getInt64Ty(M.getContext()), 1); GlobalVariable *CounterSize = new GlobalVariable(M, ATyC, false, GlobalValue::InternalLinkage,

Hello; Thanks to Eli for the pointer to the ConstantDataArray::getString() fucntion. Now I am trying to declare a global char array with the content "hi" and call a function "print" (which takes a char pointer and return an insteger. I am doing the following in the code - Function Creation: PointerType* array = PointerType::get(IntegerType::getInt8Ty(getGlobalContext())

I have a Function* to a function that has a signature like: void foo(double*, double*); I need to write the address of this function into a global variable initializer (really, into the initializer of a particular structure field). The structure field type is void*, and must be. Because of type constraints, doing something like: Function* foo = ...; std::vector<const Type*> fields; ...

I notice that there's a lot of inconsistency in the various LLVM classes with respect to convenience methods. Here's some examples: For creating GEPS, IRBuilder has: CreateGEP (2 overloads) CreateInBoundsGEP (2 overloads) CreateConstGEP1_32 CreateConstInBoundsGEP1_32 CreateConstGEP2_32 CreateConstInBoundsGEP2_32 CreateConstGEP1_64 CreateConstInBoundsGEP1_64
