[PATCH] D122573: [TBAA] Emit distinct TBAA tags for pointers with different depths,types.

[Eli Friedman via Phabricator via cfe-commits]

efriedma added a comment.

I'm a little skeptical about making TBAA more aggressive.  In most situations, we're probably talking about tiny performance gains, and currently there's no good way to check whether a codebase suffers from type punning issues (either with compile-time analysis or runtime instrumentation).  Probably LLVM itself does, but we have no way of knowing.
