[PATCH] D101103: [InstSimplify] Treat invariant group insts as bitcasts for load operands

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

While it may make sense to address this in JumpThreading in addition, I believe InstSimplify is intended to be robust against unreachable code. As InstSimplify can thread over phis, I don't think it's even possible for a caller to reliably prevent unreachable code from reaching InstSimplify.
