[Dávid Bolvanský via Phabricator via llvm-commits]

xbolva00 added inline comments.


================
Comment at: llvm/lib/Transforms/InstCombine/InstCombineCompares.cpp:4574
+  Value *Op1 = simplifyIntToPtrRoundTripCast(ICmp.getOperand(1));
+  if (Op0 != ICmp.getOperand(0) || Op1 != ICmp.getOperand(1))
+    return new ICmpInst(ICmp.getPredicate(), Op0, Op1);
----------------
... and then this code can be simplified...


================
Comment at: llvm/lib/Transforms/InstCombine/InstructionCombining.cpp:354
+  if (!Cast)
+    return Val;
+  if (Cast->getOpcode() == Instruction::IntToPtr &&
----------------
return nullptr instead Val? ...
