I noticed this while looking at a shader that was affected by Tim's
"more loop unrolling" series.
In review, Tim Arceri asked:
> Why the hurt on Gen6+ is this something that should be in the late
> optimisations pass?
As far as I can tell, it's just because our scheduler is terrible. In
all the fragment shaders that I looked at (some hurt shaders were from
other stages), only one of the SIMD8 or SIMD16 version would be hurt.
In many of those case, the other SIMD width is improved (e.g.,
shaders/closed/steam/brutal-legend/3990.shader_test).
Often it looks like the scheduler decides to differently schedule a SEND
the occurs somewhere early in the shader. Once that happens, everything
is different.
I looked at one vertex shader that was hurt (from Goat Simulator). In
that case, both the floor and fract are used. The optimization
eliminates the add, and it should allow better scheduling. In the area
of the FRC and RNDD instructions, the scheduler does the right thing.
However, later in the shader a MAD and and ADD get scheduled
differently, and that makes it slightly worse.
In light of this, I tried adding some "is_used_once" mark-up, and that
did not fix all the cycles regressions. It also did a lot more harm
than good on SKL (helped 82 vs. hurt 241).
All Gen6+ platforms had similar results. (Skylake shown)
