[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added inline comments.


================
Comment at: llvm/lib/Analysis/InstructionSimplify.cpp:4682-4686
+        for (unsigned i = 1, e = GEP->getNumOperands() - 1; i < e; ++i) {
+          if (!match(GEP->getOperand(i), m_ZeroInt()))
+            OnlyLastIndexNonzero = false;
+        }
+        Value *LastIndexOp = GEP->getOperand(GEP->getNumOperands() - 1);
----------------
Can this be something closer to this?
I'm having trouble parsing the current one..
