================
Comment at: llvm/lib/Target/AArch64/AArch64LoadStoreOptimizer.cpp:696
+    // ... the new instruction is not more complex than both old ones.
+    if (AUops > 1 || BUops > 1)
+      return NewUops <= (AUops + BUops);
----------------
Can you add more comment why you do this? Is this target independent ?
