<p class="MsoNormal">Hi Ramakota,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">You can get consumer-typeset in debug mode using the -g flag in Clang.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I don’t think this will necessarily help you a lot though. You’re debugging the compiler, not the consumer-typeset source code. Personally, I find the output assembly a bit more useful than actual test source information in this situation.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">In situations like this, it’s probably better to see if you can find a SingleSource test failure. These are usually a bit easier to work with than large MultiSource tests. If there are no such failures, you can usually narrow things down
by bisecting on object files.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">e.g.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">1) Compile consumer-typeset with a good compiler<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">2) Compile consumer-typeset with the compiler you want to debug<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">3) Link half the object files from the good consumer-typeset with half the object files from the bad consumer-typeset<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">4) Run the test and see if it fails<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">5) Repeat until you (hopefully) find one file that causes the issue<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">From there, you’re usually in a much better position to start debugging the compiler.<o:p></o:p></p>
