================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:4879
+  if (ShAmt) {
+    assert(ShAmt % 8 == 0 && "ShAmt is byte offset");
+    const unsigned ByteShAmt = ShAmt / 8;
----------------
`assert` here is just to refresh what is established L.4861
It helps understand why `ShAmt / 8` is valid.
