A simple example for recursive type may be as following.

/* C struct type */
struct foo {
  struct foo *a;
};

/* Method */
StructType *STy = StructType::createNamed(Context, "struct.foo");
PointerType *PTy = STy->getPointerTo();
std::vector<Type*> Elements;
bool isPacked = false;
Elements.push_back((Type*)PTy);
STy->body(Elements, isPacked);

/* Result of llvm IR */
%struct.foo = type { %struct.foo* }
