RX 480 with llvm 4.0.0svn_r290670, mesa git
Tested with linux 4.9 and 4.10-rc1, happens on both. Tested with ingame settings medium and highest, happens with both.
This apitrace hangs my GPU: https://haagch.frickel.club/files/stanley_linux.trace.xz

Apparently this didn't attach correctly when I created the bug.
Thanks for reporting this.
I can reproduce the hang on rx 480 with latest mesa/llvm git.
It hangs at drawcall 674985.
I will investigate.
It's actually a regression in mesa, works fine with 13.0.2.
After bisecting, the first bad commit is:

radeonsi: don't export ClipVertex and ClipDistance if clipping is disabled
This is the first user of optimized monolithic shader variants.
Cull distances can't be disabled by states.

But this doesn't seem to be actually related to the clip planes optimization because
if you replay the trace with R600_DUMP_SHADERS=y, it no longer crashes. If my understanding
is correct, it won't compile shaders asynchronously. Forcing num_compiler_threads = 1 in
si_pipe.c also "fixes" the hang.
This should fix it:
The game runs without hangs now. Thanks.
