LLVM is in the midst of converting to opaque pointers, where all pointers become
a single opaque pointer type that does not indicate what the type the pointer is
pointing to. Writing any new code that relies on the types that pointers point
to will shortly (on the order of months) fail to work entirely.
If you’re dead-set on writing code that will work at best temporarily, you can
compute the pointer level by iterating T = T->getPointerElementType() and
counting how many times before you arrive at a non-pointer type.

Subject: [llvm-dev] Find the level of pointers
Hi,
How can I find the level of the pointer variable? I need to differentiate
between **i32 and ***i32. Is there any way to do this? getType() will return
pointer type. But if I wanted to get 2 from **i32 and 3 from ***i32, is there a
way?
Thanks,
Haritha Madhav C
