Philip, I tried to reproduce by cloning git://anongit.freedesktop.org/drm/drm-tip, but I don't understand the URL in the report. Were Maarten's patches on top of drm-tip? Is there a tree you found them from (rather than me fetching the 0day branch on github)? (Or maybe this is what a report looks like for a series posted to the list?) Apologies for the naivete, but I plan to triage as many of these reports on the Clang side as I can in my free time, so I want to make sure I understand precisely what failure is occurring where and how. -- Thanks, ~Nick Desaulniers _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
