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

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

Okay, I'm past the GEP "have to dereference pointer first" problem of my last post. I now have a linkage error (I get undefined symbol when I try to assemble the program). gcc -o test.o test.s says: > /tmp/cczhiFk7.o(.text+0x7): In function `a': > : undefined reference to `_index_' _index_ is defined like this: > %_index_ = external global long ;

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] =

Hi All, I am trying to write code for simple instrumentation. What I want to do is to insert a call to an external function for result of each conditional branch instruction. This external function simply print true or false based on the result of condition. The modified code is then written into new file. However when I try to link that file with another bitcode file (containing external

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 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

[Reposted from llvm-bugs mailing list. Also has an updated, hopefully better, patch associated with it.] Hi, The following program causes the LLVM GCC4 front end to ICE: struct A { virtual ~A(); }; template <typename Ty> struct B : public A { ~B () { delete [] val; } private: Ty* val; }; template <typename Ty> struct C : public A { C (); ~C (); }; template

You can also see the resulting module by using -disable-verify: $ opt -yourpass -disable-verify < file.bc | llvm-dis You may see what the problem is by looking at the LLVM assembly. -- Misha Brukman ::

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())

Have you tried running the verifier after ConditionProfile runs? Just add it to the pass manager to run right afterwards and see what it picks up.
