[PATCH] D157800: [ValueTracking] Improve analysis of knownbits from incoming phi edges.

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/lib/Analysis/ValueTracking.cpp:1530
               default:
-                // TODO - add additional integer predicate handling.
                 break;
               }
----------------
Can this code be reduced to `ConstantRange::makeExactICmpRegion()` + `ConstantRange::toKnownBits()`?
