[Xiang Zhang via Phabricator via llvm-commits]

xiangzhangllvm added a comment.

The small test case is easy to reproduced on llvm.14  PLS refer EY93Kc77E <https://godbolt.org/z/EY93Kc77E>
it continue to do the combine (  gen  vpsubb  +  vptest  ) even there is more uses of the cmp result.

but hard to reproduce on llvm trunc. (But the bug is still here)
