Regarding BDCE: The trivialized values might indeed be irrelevant to<br>
later calculations, but might harm the debugging experience? If BDCE<br>
only was applied at O2 and higher, that's likely not a huge loss.<br>
Regular DCE (meaning without the bit-tracking parts) is probably fine<br>
for O1.<br><br><br></blockquote><div><br></div><div>Probably not. I'll see what the impact is for sure.</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

I'm not sure about this - we should understand the performance impact -<br>
it might be severe.<br><br></blockquote><div><br></div><div>Totally agree. I think evaluating the tradeoffs is going to be key. I also have really no strong opinions and am happy to go where the data takes us.</div><div><br></div><div>Thanks :)</div><div><br></div><div>-eric</div></div></div></div>
