<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Slava, if you have added files/directories under llvm-project/ then you no longer have an *unmodified* llvm-project. You have added something to
it, and it is appropriate to modify .gitignore to allow for that. If that is the only file you have to modify, then you have the second-cheapest possible downstream situation. (The only way to make it cheaper is if all your downstream additions are siblings
of llvm-project/ rather than children.)<o:p></o:p></span></p>
