[Gerolf Hoflehner via llvm-commits]

Thanks for following up!
LGTM



================
Comment at: lib/Target/AArch64/AArch64ISelLowering.cpp:7650
+  // Use ConstantA instead of ConstValue to support both shift+add/sub and
+  // shift+add+shift.
+  APInt ConstantA = ConstValue.ashr(TrailingZeroes);
----------------
CAMinus1 is consistent with the comment. Perhaps ConstantAMinus1 would be even more clear.
