[Dávid Bolvanský via Phabricator via llvm-commits]

xbolva00 added inline comments.


================
Comment at: llvm/lib/Transforms/Scalar/LoopIdiomRecognize.cpp:110
 
 STATISTIC(NumMemSet, "Number of memset's formed from loop stores");
 STATISTIC(NumMemCpy, "Number of memcpy's formed from loop load+stores");
----------------
Also you can add NumMemMove..


================
Comment at: llvm/lib/Transforms/Scalar/LoopIdiomRecognize.cpp:1380
     MSSAU->getMemorySSA()->verifyMemorySSA();
-  ++NumMemCpy;
+  if (!UseMemMove)
+    ++NumMemCpy;
----------------
… and increment it here
