<div class="">Some time ago you implemented a sext(add_nsw(x, C)) --> add(sext(x), C_sext) transformation in X86ISelLowering </div>


<div class=""><a href="https://reviews.llvm.org/D13757" class="">https://reviews.llvm.org/D13757</a></div>


<div class="">Is there any reason why this transformation is limited to sexts and doesn’t support zexts?</div>

<div class="">Thanks,</div>
