[PATCH] D62818: [InstCombine] Change order of ICmp fold.

[Huihui Zhang via Phabricator via llvm-commits]

huihuiz added a comment.

Yes , changing the order would allow these folds.

  (X & (signbit >> Y)) != 0  ->  (X << Y) s< 0
  (X & (signbit >> Y)) == 0  ->  (X << Y) >= 0
  ((X << Y) & signbit) != 0  ->  (X << Y) s< 0
  ((X << Y) & signbit) == 0  ->  (X << Y) >= 0
