[PATCH] D57921: [DAG] Cleanup unused node in SimplifySelectCC.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:18677
   SDValue SCC = SimplifySetCC(getSetCCResultType(CmpOpVT), N0, N1, CC, DL,
                               false);
+  if (SCC.getNode()) {
----------------
Could we replace this with a call to SelectionDAG::FoldSetCC()? That should only ever constant fold which AFAICT is what we're after.
