          <p>Hi</p>

          <p>Regarding: <a class="moz-txt-link-freetext" href="https://reviews.llvm.org/rL180834">https://reviews.llvm.org/rL180834</a><br>

          </p>

          <p>I tried my old patch for InstCombiner for shuffles, which

            was a handling for <a

              href="https://bugs.llvm.org//show_bug.cgi?id=30630"

              class="remarkup-link" target="_blank" rel="noreferrer">https://bugs.llvm.org//show_bug.cgi?id=30630</a>.

            When I applied it a month ago, it produced nearly no change.

            But now I do see some files that needs this optimization,

            and I suspect it has to do with this revert.

          </p>

          <p>I wonder what the status is on getting this reverted patch

            recommitted? Should I post my patch for InstCombiner on

            Phabricator?</p>
