(In reply to comment #11) > Can you test this branch: > http://cgit.freedesktop.org/~tstellar/llvm/log/?h=si-spill-fixes-v2 I'm using 3.15-rc3 by now and I don't know whether it's fixes in linux or fixes in llvm, but there are no gpu faults and no crashes anymore. At least for the few minutes I have "tested" for now it worked absolutely fine. Awesome!
