[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

Thanks again for looking at this!



================
Comment at: llvm/lib/Analysis/ValueTracking.cpp:1217
+        Known.One |= KnownSrc.One.zext(BitWidth).shl(ShiftAmt);
+        Known.Zero |= KnownSrc.Zero.zext(BitWidth).shl(ShiftAmt);
+      }
----------------
Can you use APInt::insertBits here ?
