--- Comment #6 from Maciej S. Szmigiero <mail@maciej.szmigiero.name> ---
There are really two issues at play here:
1) If the LLVM-generated code cannot be run properly then it should be simply
rejected by whatever is actually in charge of submitting it to the GPU (I guess
this would be Mesa?).
This way an application will know it cannot use OpenCL for computation, at
least
not with this compute kernel.

Instead, it currently looks like many of these test run but give incorrect
results, which is obviously rather bad.

2) Some (previous) Mesa + LLVM versions generate a command stream that crashes
the GPU and, as far as I can remember, sometimes even lockup the whole machine.

It should not be possible to crash the GPU, regardless how incorrect a command
stream that userspace sends to it is - because otherwise it is possible for
an unprivileged user with GPU access to DoS the machine.
