<div class="">Hi,</div>
<div class=""> </div>
<div class="">I have target specific intrinsics (X86 in my case) with special constant parameters.</div>
<div class="">Rounding mode constant, or scale value in gather/scatter. The scale, for example, may be 0, 1, 2, 4, or 8 only. </div>
<div class="">How do I verify the values on IR level ?</div>
<div class=""> </div>
<div class="">I’m looking at <font face="Consolas" color="#2B91AF" class="">Verifier</font><font face="Consolas" class="">::visitIntrinsicFunctionCall</font><font face="Consolas" class="">()</font></div>
<div class="">but I see only common intrinsics here, not target specific.</div>
<div class=""> </div>
<div class="">Thank you.</div>
