[PATCH] D79112: [SelectionDAG] Add the option of disabling generic combines.

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:1655
+  SDValue RV;
+  if (!STI || !STI->disableGenericCombines(OptLevel))
+    RV = visit(N);
----------------
Why call this for every node? Why not just once when the combiner is constructed?
