nikic added inline comments.


================
Comment at: llvm/lib/Transforms/InstCombine/InstCombineAndOrXor.cpp:1991
+  // An and recurrence w/loop invariant step is equivelent to and start, step
+  if (SQ.DT) {
+    PHINode *PN = nullptr;
----------------
DT is required in InstCombine. You should also be able to use DT directly without going through SimplifyQuery.
