================
Comment at: llvm/include/llvm/IR/Type.h:491
+  [[deprecated("Pointers no longer have element types")]]
+  inline PointerType *getHalfPtrTy(LLVMContext &C, unsigned AS = 0) {
+    return getInt8PtrTy(C, AS);

Ah right, ofcourse. Now I got it!

Great catch. But then I think I'll just follow up with at patch that removes these functions (no one has complained so far anyway, and right now it is broken).
