[PATCH] D58650: Add support for computing "zext of value" in KnownBits. NFCI

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/trunk/include/llvm/Support/KnownBits.h:120
+  /// With ExtendedBitsAreKnownZero=false the extended bits are set to unknown.
+  KnownBits zext(unsigned BitWidth, bool ExtendedBitsAreKnownZero) {
+    unsigned OldBitWidth = getBitWidth();
----------------
Might be clearer to separate this into a `zext` and an `anyext` method?
