================
Comment at: llvm/lib/Target/AArch64/AArch64InstrInfo.cpp:2190
+        (MI.getOperand(1).getReg() == AArch64::SP ||
+         MI.getOperand(1).getReg() == AArch64::WSP))
+      return MI.getOperand(0).getReg();
----------------
Why does it matter if the address computation SP, as opposed to the frame pointer or a scratch register?  It's a load from a stack slot either way.
