[PATCH] D87994: [LangRef] Clarify the behavior of memory access instructions when pointers/sizes aren't well-defined

[Evgenii Stepanov via Phabricator via llvm-commits]

eugenis added a comment.

MSan will complain about any undefined bits in a pointer.
We have not seen a false positive caused by this so far, but it sounds like we should relax the requirement. Does it make sense for MSan to allow undef in the lower bits up to the known dereferenceable range of the pointer?
