<b>Subject:</b> [llvm-dev] Why do constant SD nodes not set the IROrder?<o:p></o:p></p>
</div>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Specifically I would like to understand why ConstantSDNode and ConstantFPSDNode do not set the IR ordering like most other SDNode-s. These constant SD nodes also previously did not set the debugloc, but that got enabled (here:
<a href="http://llvm.org/viewvc/llvm-project?view=revision&revision=237237">http://llvm.org/viewvc/llvm-project?view=revision&revision=237237</a>).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">These constant SD nodes hard-code the order to 0. Is this intentional, or just something that has not been handled yet? I have a case for debug support where I think this is needed.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
