[PATCH] D88072: [X86] Improve demanded bits for X86ISD::BEXTR.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/lib/Target/X86/X86ISelLowering.cpp:38352
+        Known = Known.zextOrTrunc(BitWidth);
+        return false;
+      }
----------------
Maybe just call computeKnownBits to avoid code duplication?
