Comment at: llvm/include/llvm/CodeGen/TargetLowering.h:4400
+  /// Expand BSWAPxa nodes. Expands scalar BSWAP nodes. Returns SDValue()
+  /// if expand fails.
+  /// \param N Node to expand
----------------
IIRC we handle vector nodes as well? we handle any i16/i32/i64 scalar/vector case - so maybe say something like that?
