[PATCH] D148986: [InstSimplify] with logical ops: (X | Y) ? 0 : X --> 0

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Analysis/InstructionSimplify.cpp:4733
+      match(TrueVal, m_ZeroInt()) && Pred == ICmpInst::ICMP_NE)
+    return TrueVal;
+
----------------
Also - is this safe when matching zero vectors with undef elements?
