================
Comment at: lib/Target/AArch64/AArch64ISelLowering.cpp:7440
     // 9-bit signed offset
-    if (Offset >= -(1LL << 9) && Offset <= (1LL << 9) - 1)
+    if (Offset >= -(1LL << 8) && Offset <= (1LL << 8) - 1)
       return true;
----------------
It would probably be better to use llvm::isInt<9>.
