llvm dev - Nov 2013 - [LLVMdev] about creating the first value of the storeinst

Dear All

I'm trying to create storeInst using

StoreInst *SI = new StoreInst(val, AI, BB);

AI is an alloca instruction previously created, BB is the basicBlock I want to
put instructionsi in. Val is the value to store.

I've created val from a genericValue like this:

Value* val = ConstantInt::get(getGlobalContext(), Result.IntVal);

Result is the genericValue

However I keep getting this error:

void llvm::StoreInst::AssertOK(): Assertion `getOperand(0)->getType() ==
cast<PointerType>(getOperand(1)->getType())->getElementType()
&& "Ptr must be a pointer to Val type!"' failed.


What is wrong about my code?


Thanks a million in advance.

It worked. I managed finally to create the StoreInst.

The problem was in AllocaInst from the start. I was passing a wrong type for
CreateAlloca function so it was generating a wrong pointer.
