[Mesa-dev] [PATCH 0/5] i965/vec4_nir: Various fixes for ILK- and BDW+

[Jason Ekstrand]

This is a quick little series that fixes a bunch of piglit regressions with
vec4 NIR on ILK- and BDW+.  With this series, vec4 NIR has (I think) zero
regressions versus non-NIR on all intel platforms.  I haven't yet tested
NIR with vec4 vertex shaders on BDW, but I think it's probably ok.  We
should definitely verify that at some point.

I'm not 100% sure what I think about the first two patches.  They actually
end up canceling each other out in effect.  However, I do think that the
end result is better.  Opinions welcome.

Jason Ekstrand (5):
  i965/nir: Use nir_op_info.output_type for determining when to resolve
  i965/nir: Don't mark bany or ball instructions for resolve
  i965/vec4-nir: Handle boolean resolvese on ILK-
  i965/vec4_nir: Do boolean source modifier resolves on BDW+
  i965/vec4_nir: Properly handle integer multiplies on BDW+
