<pre>Filed the 'lshr' pattern as <a class="bz_bug_link
bz_status_NEW "
title="NEW - [InstCombine] remove unnecessary truncate"
href="show_bug.cgi?id=50575">bug 50575</a>.
The example pasted in the description is transformed into that (ashr->lshr).
But the bug title and the example in the godbolt link in the description are
different and should be fixed with:
<a href="https://reviews.llvm.org/rGb865eead7657">https://reviews.llvm.org/rGb865eead7657</a>
So I think it's ok to close this one, but feel free to reopen or file new bugs
to track other items.</pre>
