ok.. you are right. I had not inserted the AllocaInst in the function.

...new AllocaInst(Type::Int32Ty); Value *ST = new StoreInst(Ten,AI,false,4,j); Value *BT = new BitCastInst(ST,VoidPtrTy,"",j); CallInst *CallPrint = CallInst::Create(myprint, BT, "", j); CallPrint->setTailCall(true); I am getting the following error while executing. Assertion `castIsValid(getOpcode(), S, Ty) && "Illegal BitCast"' failed. What am I doing wrong :(? I always get stuck badly when these assertions fail :(. Please help me out here.

Hello all .. my first post to this thread (and this list, as it happens)..

Dear All I'm making an instrumentation pass. The pass is supposed to modify the given IR in a specefic way. One of the required modifications is to insert a call to a function at a specific location. This is the signature of the called function: void myclass::foo(Function *f, BasicBlock* b) This function's prototype is in an foofile.h file in include/llvm And the function
