--- Comment #4 from Eero Tamminen <eero.t.tamminen at intel.com> ---
After Jason's "nir, i965/fs: Lower indirect local variables to scratch"

Mesa freeze spends its time in "instruction_scheduler::add_dep".

After maybe 10 minutes, Mesa outputs:
compute shader triggered register spilling.  Try reducing the number of live
scalar values to improve performance.
Mesa 13.1.0-devel implementation error: Failed to compile compute shader: CS
compile failed: Register spilling not supported with m14 used

Please report at https://bugs.freedesktop.org/enter_bug.cgi?product=Mesa
Signal 11 caught.
EngineCrashHandler: Signal=11
