[PATCH] D44891: [RFC][Memory Dependency Analysis] Not clobber load value by store if the store value won't change load content

[Daniel Berlin via Phabricator via llvm-commits]

dberlin added a comment.

This isn't correct in the face of atomics and volatiles, and IMHO, MemoryDependence should not be performing this optimization.
If you want, teach GVN to requery MemDep in these cases.
