[PATCH] D74539: [KnownBits] Avoid copying KnownBits objects

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Analysis/ValueTracking.cpp:1097
 
-  KnownBits Known2(Known);
+  KnownBits Known2(BitWidth);
   switch (I->getOpcode()) {
----------------
Not sure about the std::move but using BitWidth makes sense to me.
