[PATCH] D111968: [TTI] Add OperandValueProperties::OP_NegatedPowerOf2 enum

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Analysis/TargetTransformInfo.cpp:673
       OpProps = OP_PowerOf2;
+    else if ((-CI->getValue()).isPowerOf2())
+      OpProps = OP_NegatedPowerOf2;
----------------
I'm starting to think a APInt::isNegatedPowerOf2() wrapper might be useful?
