[PATCH] D148420: [InstSimplify] Enhance select icmp and simplification

[Noah Goldstein via Phabricator via llvm-commits]

goldstein.w.n added inline comments.


================
Comment at: llvm/lib/Analysis/InstructionSimplify.cpp:4411
+  const APInt *C;
+  if (Pred != ICmpInst::ICMP_EQ ||
+      !match(AndVal, m_And(m_Specific(X), m_APInt(C))))
----------------
Can we also handle `select (icmp ne (and X, C), 0, (shl X, K), 0)`?
