<div dir="ltr">Hello,<br><br>This is the summary of my Community bonding period week 2, as planned I spent some time reading loop transformation passes present in lib/Transforms/, I tried to find the code motion checks in transformation passes. I was able to find some worthy code motion checks in transformation passes, I also looked into the Phabricator review D71578 to get familiar with PR and writing unit tests. isSafeToMoveBefore uses DFS numbering for determining the relative position of instruction and insert point which is not always correct, I tried to replicate and fix a test case by using dominator tree level to decide the direction of code motion and posted a PR (Phabricator review D80084).<br><br>Best Regards,<br>Rithik Sharma</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, 12 May 2020 at 00:03, RITHIK SHARMA <<a href="mailto:rithiksh02@gmail.com">rithiksh02@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt" id="gmail-m_-8118014097210328249gmail-docs-internal-guid-3cebf99c-7fff-da28-095c-dcb0af30313f"><span style="font-size:11pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre-wrap">Hello,</span></p><br><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt"><span style="font-size:11pt;font-family:Arial;color:rgb(0,0,0);background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre-wrap">This is the summary of my Community bonding period week 1, as planned I spent some time reading loop analysis passes present in lib/Analysis/, I tried to find the code motion checks in these analysis passes.
