[PATCH] D137721: [AArch64] Optimize more memcmp when the result is tested for [in]equality with 0

[chenglin.bi via Phabricator via llvm-commits]

bcl5980 added inline comments.


================
Comment at: llvm/lib/Target/AArch64/AArch64ISelLowering.cpp:8553
+  // The leaf node must be XOR
+  if (N->getOpcode() == ISD::XOR) {
+    WorkList.push_back(std::make_pair(N->getOperand(0), N->getOperand(1)));
----------------
Can ISD::SUB be leaf node also?
