<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">The names would show up in dumps of the IR (e.g. “call F.dump()” from gdb) , which was really handy for debugging. But with LLVM 3.6’s split of Value and MDNode, the naming
facility seems to have disappeared. Is there a way with LLVM 3.6 or later to name MDNodes in a way that will show up in IR dumps?<o:p></o:p></span></p>
