<p class="MsoNormal">Is it possible to somehow similar to how DWARF functions with assembly find out which line numbers in unoptimized code are associated with which bitcode instructions for the purpose of debugging compiler passes? I am curious about whether
this is possible prior to writing some instrumentation passes for the purpose of debugging them.<o:p></o:p></p>
