--- Comment #45 from filipp.andjelo at gmail.com ---
Thank you very much for your help farmboy0. I was able to build and run
everything as you mentioned. First of all, my systems doesn't hang as you
describe in Comment 21, all the games are (kind of) running.
I tested master branch of llvm as well as
http://cgit.freedesktop.org/~tstellar/llvm/log/?h=si-spill-fixes-v3. Both
versions don't crash anymore, but the performance is very bad. With master
branch the games are stuttering heavily, every 2-3 seconds the application
stops for a second. With the si-spill-fixes-v3 everything's running a bit
smoother, but still very slowly. Feels like similar behavior in both cases, but
using si-spill-fixes-v3 it feels like the games would "wait" for shorter period
of time, therefor more often. I tested with both 64 and 32 bit builds.
