The commit > updates mesa so it seems quite possible. Woohoo, congrats! Really great to finally nail this down. One thing that might be worth a try before bisecting Mesa itself is building against LLVM 3.9.1 again. I don't know the relevance of the "exactly 3.9.1 for swrast" comment from that commit. We should also check whether this problem is fixed in 18.2 (available in the 'staging' branch). Out of curiosity, which graphics driver are you using? > I don't have that much time right now but I will try to revert the two > commits found so far and see whether this gets OpenGL running again on > the master branch.
