[PATCH] D28216: AVX-512: Truncate with unsigned saturation.

[Elena Demikhovsky via Phabricator via llvm-commits]

delena updated this revision to Diff 83798.
delena added a comment.

The previous patch was reverted due to a failure (https://llvm.org/bugs/show_bug.cgi?id=31589).

1. I fixed the bug and added a lot of test cases.
2. I promised to Simon to cover non-avx512 cases with VPACKUS. Now it is in. Additional tests are in avx-trunc.ll.
