[PATCH] D69387: [ConstantRange] Add toKnownBits() method

[Nikita Popov via Phabricator via llvm-commits]

nikic added a comment.

Possible use case: A better implementation for `binaryAnd`/`binaryOr`. Conceptually, those can be implemented by doing:

  KnownBits Known = toKnownBits();
  KnownBits OtherKnown = Other.toKnownBits();
  
  // and
  Known.One &= OtherKnown.One;
  Known.Zero |= OtherKnown.Zero;
  
  return fromKnownBits(Known, /* IsSigned */ false);
