Sticking it in GVN is another option, but again I'm concerned about it running before SLP. Maybe it can run in the SLP pass after the main algorithm.<br></blockquote><br style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><span style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; float: none; display: inline !important;">In this case wouldn't it be just as easy to make it a separate pass that runs after SLP?</span></blockquote></div><br><div>Yes, I thought we might be avoiding pass proliferation though. I’m neutral on that. The main things I’m concerned with is that it doesn’t interfere with SLP and is generally profitable.</div><div><br></div><div>-Andy</div></body></html>
