Hello, I am writing an optimization pass which optimizes code based on an online pointer analysis algorithm and need to detect pointers which are pointing to derived types. I have not had any problem identifying pointers in general using isa<PointerType>(...), but I can't seem to figure out how I can make sure that the pointer is pointing to a scalar value and not a function, array,

...ere $struct.S is defined as a struct %struct.S = type { i32, i32 } I'm using the following loop: for(inst_iterator i = inst_begin(F), e = inst_end(F); i!= e; i++) { AllocaInst* ai; if( (ai = dyn_cast<AllocaInst>(&*i))){ if(ai->getOperand(0)->getType()->getTypeID() == Type::StructTyID) allocs.push_back(ai); } } However, I had the impression that the type comparison can be done by a pointer comparison. Can anyone please suggest me a better way to do it? Also, I want to get the size of %struct.S, should I use the following code? const Target...

...program. I could detect function pointer calls using the getCalledFunction(). However,i am stuck in identifying function pointer declaration and use. is there a way one can distinguish between data and function pointers in llvm? I tried the following, I->getType()->getElementType()->getTypeID() but this always returns me 12 i.e pointer type id (for pointers) irrespective if the pointer is a data or a function pointer. Kindly let me know where i am going wrong. Regards, Netra Mtech,CSE,IIT BOMBAY
