<p style="margin-top:0;margin-bottom:0"><br>

<p style="margin-top:0;margin-bottom:0">I am building the SPEC 2006 Benchmark with Clang as the compiler. I have written a function pass in LLVM and I am trying to run that for SPEC by invoking the pass in the build options of SPEC. The build options of SPEC
are in a *.cfg config file, which allows us to specify the choice of compiler while building SPEC. (<a href="https://www.spec.org/cpu2006/Docs/install-guide-unix.html" class="OWAAutoLink" id="LPlnk885594" previewremoved="true">https://www.spec.org/cpu2006/Docs/install-guide-unix.html</a>)</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">The pass runs for several functions, but llvm crashes at a certain point. I am checking dependencies between various loops in a function in that pass.</p>
