--- Comment #12 from Eero Tamminen <eero.t.tamminen at intel.com> ---
Tested latest Mesa.  On my SKL GT2 the slow shader still takes ~20s to compile
and produces following Mesa statistics:
SIMD8 shader: 7985 instructions. 0 loops. 57210 cycles. 359:993 spills:fills.
Promoted 19 constants. Compacted 127760 to 86032 bytes (33%)
