What does this nm output "V typeinfo name for void*" mean?

Question

Could you please tell me what do these pieces of nm's output mean?

$nm --demangle --dynamic --defined-only --extern-only lib.so

0000000000238ba0 V typeinfo name for void*

0000000000238b80 V typeinfo for void*

What are the C++ constructs they are generated for?

I've searched the Internet but didn't find the explanation.

Answer 1

At the risk of giving the obvious answer, that's just the data needed for typeinfo(void*). What else would it be?
