[PATCH] D116886: [M68k] Instruction selection to choose neg x when mul x -1 (Fix issue 48588)

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Target/M68k/M68kISelDAGToDAG.cpp:327
+      if (llvm::isNullConstant(U->getOperand(0)))
+        return false;
+    }
----------------
(style) Add a break - even though its the last case in the switch() its good practice to use them.
