Hi all, as a LLVM beginner I would like to know how can i check the pointer types with different levels like int 32* and int 32**, int 32***?

By using value->getType()->isPointerTy() i can just know they are pointers. But the dump results clearly show they are different. Is there a good way to calculate their actual point to levels? Thanks!

You will need to use dyn_cast to cast the Type * into a PointerType *. Once you do that, you can find the Type * that the PointerType points to.
