[PATCH] D144677: [SelectionDAG] Transitively copy NodeExtraInfo on RAUW

[Marco Elver via Phabricator via llvm-commits]

melver added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/SelectionDAG.cpp:12202
 
+  // We need to copy NodeExtraInfo to all _new_ nodes that are being introduced
+  // through the replacement of From with To. Otherwise, replacements of a node
----------------
RFC: Is there some other property of the DAG and the nodes that could be exploited to make this more efficient?
