<div>
<p class="MsoNormal">Hi, all. I'm trying to analyze SPECInt 2006 with LLVM and face errors on some programs. <o:p></o:p></p>
<div>
<p class="MsoNormal">I modified the configuration in makefile tree so that each source code generates its byte code instead of an object file. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Then, I combined all the generated byte codes into a single byte code and run it directly with lli. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">The approach works with several benchmarks (e.g. bzip) but not all of them. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Certain benchmarks like "471.omnetpp" or "483.xalancbmk" halt their execution with segmentation fault. Interestingly, both benchmarks are implemented C++. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Do I need to add certain optimization flag? <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I'm only using the flags as follows: -static -emit-llvm -O2<br clear="all">
<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Any advice will be a great help.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Thank you!<o:p></o:p></p>
