<div dir="ltr"><div><div>Hi,<br><br></div>I am trying to tune flags for SPEC2006's libquantum. <div><br></div>I am looking for a set of flags that I can use to start with. I found this thread:<br><br><a href="http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-January/069430.html">http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-January/069430.html</a><br>
</div><div><div><br></div><div>Are there flags other than:<br><br>-mllvm -vectorize-num-stores-pred=1 -mllvm enable-loadstore-runtime-unroll -mllvm -enable-ind-var-reg-heur <br><br></div><div><pre>I think I need to use -O3 -flto -emit-llvm with the compile command and -flto -O3 at linking, to enable LTO.<br>
<br>Appreciate pointers on other SPEC INT programs <br><br></pre><pre>Best,<br>Ramshankar<br></pre><pre><br></pre><br></div></div></div>
