[PATCH] D149198: [DAGCombiner] Make it so that `udiv` can be folded with `(select c, NonZero, 1)`

[Dávid Bolvanský via Phabricator via llvm-commits]

xbolva00 added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:2391
+  // We can't hoist all instructions because of immediate UB (not speculatable).
+  // For example div/rem by zero.
+  if (!DAG.isSafeToSpeculativelyExecuteNode(N))
----------------
