This should say 64.

Is this a room to add a note? or I missed some related sections?

This is specified in https://llvm.org/docs/LangRef.html#id209 and https://llvm.org/docs/LangRef.html#id214. But current semantics are not really clear/inconsistent, see also discussion on D123991 <https://reviews.llvm.org/D123991>.
