<div dir="ltr"><div>Hi all,<br><br></div>This email is to serve as a reminder in regards to my previous email querying about the present implementation of PRE in LLVM.<br><br>In
case the present scope of PRE in LLVM is as I mentioned my previous
email, which is fairly restricted, than I would like to take it up as a
GSoC project to extend the scope of PRE in LLVM.<div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div>Thanks,</div>Aradhya Biswas,<br>Final Year Undergraduate Student,<div>Department of Computer Science and Engineering,<br>Indian Institute of Technology Hyderabad<br><div style="display:inline"></div><div style="display:inline"></div></div></div></div></div>

studying the compiler optimization theory, LLVM always served as best
tool for experimenting. But recently when I came across the concept of
Partial Redundancy Elimination, I could not find any exclusive
implementation of it in the present LLVM framework. On digging a little
deeper, I could find that the implementation of GVN subsumes the load
PRE and a specific case (namely, the diamond case) of scalar PRE in the
present LLVM framework. <br><br><span>I had two question in this regards :<br></span></span></div><ol><li><span style="color:rgb(0,0,0)">Where can I find the theory related to load PRE implemented <a href="http://llvm.org/docs/doxygen/html/GVN_8cpp_source.html" target="_blank">here</a> (line no. 01517) ?</span></li><li><span style="color:rgb(0,0,0)">Are there any other implementation of PRE in the present LLVM framework ? </span></li></ol><div><span style="color:rgb(0,0,0)">Thanks,</span></div><span style="color:rgb(0,0,0)">Aradhya Biswas<br>Final Year Undergraduate Student,<br>Department of Computer Science and Engineering,<br>Indian Institute of Technology Hyderabad</span></div></div>
