<p class="MsoNormal"><span style="color:#1F497D">> </span>I'm not sure exactly how step 3.a works. Does it stem from step 4.b which assigns the same eh_state to two catch handlers? It seems like these rules would come into play in these examples:<o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Yes. That’s the case I’m trying to handle with the 3a fixup. In the final implementation I hope to come up with something cleaner (maybe looking ahead when
the state is assigned in the first place), but the result will be the same.<o:p></o:p></span></p>

</span><span style="font-family:"Arial","sans-serif";color:#222222">I guess we can do the EH state assignment in the preparation pass, so long as it's resilient to basic block reordering.</span><span style="font-family:"Arial","sans-serif";color:#1F497D"><o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I think the EH state assignment (that is, the actual numbering) depends on control flow rather than physical block ordering, so I expect that the prepare pass
will be the right place to do it. Then, as you say, the IP to State table will be constructed later.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I guess we can work out the details while reviewing patches, but I’m happy to use some combination of intrinsics as you suggest.<o:p></o:p></span></p>
