--- Comment #49 from Jakub Okoński <jakub at okonski.org> ---
I double checked the SPIR-V specification, and I think this shader is invalid.

> 3.32.20 OpControlBarrier
> This instruction is only guaranteed to work correctly if placed strictly
> within uniform control flow within Execution. This ensures that if any
> invocation executes it, all invocations will execute it. 
> If placed elsewhere, an invocation may stall indefinitely.

I guess RADV and/or AMD hardware can handle this case? Or maybe it's compiled
differently?
