I show you the trace of calls to llvm that my compiler makes to generate the code above. bloques.back().last is of type Value* and bloques.back().bl is BasicBlock* (the current Block) bloques.back().last = dyn_cast<Value>(ConstantInt::get(Type::getInt32Ty(getGlobalContext()), $1, true)); // $1 is an int AllocaInst *alloc = new AllocaInst(

How are you checking the return value? I put your code in santos.ll and then executed it with lli, and I get 1 as a return value. lli santos.ll ; echo $? 1 Joey On 27 May 2012 16:59, Santos Merino <santitox at hotmail.es> wrote: > I show you the trace of calls to llvm that my compiler makes to generate > the > code above. bloques.back().last is of type Value* and

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

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

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,

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())

hi, im creating a music application(image below). At the moment im using tcc compiler but im moving across to clang because of the improved compiler warnings. Can anyone please explain and show code so I can use clang's JIT to call functions in my application? Thanks. http://old.nabble.com/file/p29449300/51709341.jpeg -- View this message in context:

I'm trying to create a global variable initialized to zero, and return its value from a newly created function, in JIT context. I'm keeping all types as i32 for the moment, and I only have the one module object. This is the code I have for creating the global variable: const Type *type = Type::getInt32Ty(getGlobalContext()); // Constant *zerov = Constant::getNullValue(type); Constant

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] =

Hello LLVMDev List, It's my first time sending a message to the List - I have been working on a tool for my research project using LLVM. Thanks for your awesome work! I have come across some bytecode like the following with an GetElementPtr instruction in brackets: Bytecode:%3 = call i32 @_Z4funcPKc(i8* getelementptr inbounds ([5 x i8]* @.str2, i32 0, i32 0)) C++ code:func("bleh");

Hi All, I'm new to LLVM and I'm having a coding problem. I'm creating a GlobalVariable that contains a StructType that contains a Function. The function returns i32 and takes two i32's. Here is my code: GlobalVariable* retrieved = module->getGlobalVariable("myGV"); ... Constant* result = ConstantExpr::getGetElementPtr(retrieved, indices); How do I get my Function

Also, you have written them in some kind of C-style idiom. What are the declarations

Hello all; So my goal is to insert some (self-written) function calls in the LLVM IR. I can achieve it with a ModulePass and using the getOrInsertFunction() call. For a ModulePass I follow the steps- 1. Compile the code (in which call instructions are to be inserted) to LLVM IR 2. Compile the file (which contains the *called* external function ) to LLVM IR 3. Link them together and run the

I am trying to get a handle on IR builder, at least some basics. I ran through a tutorial here: Create a working compiler with the LLVM framework, Part 1 <http://www.ibm.com/developerworks/library/os-createcompilerllvm1/>, and it worked well enough. I have some simple code that creates a hello world IR. I am trying to now bring in some concepts from the Kaleidoscope tutorial, namely
