[Mesa-dev] [PATCH 0/9] Various NIR fixes

[Jason Ekstrand]

This series contains a variety of fixes for NIR.  One of them (by Matt) is
a substantial shader-db fix.  Thanks, Matt, for figuring out a much easier
way to do that.  A bunch of the rest are to get NIR working on older gens.
With this series, NIR looks good on Jenkins.

Patches 2 and 9 are to the way that we determine whether or not to use NIR.
The first makes it substantially smarter so that we can use INTEL_USE_NIR
as either a force-enable or force-disable.  The last patch (number 9)
enables NIR by default for fragment shaders on SNB+.  I'm not sure that we
actually want to do this now, but the shader-db numbers are looking pretty
good on SNB+ so I figured I'd send the patch.  On ILK-, the numbers aren't
quite so good.  I'm going to look that tonight or tomorrow.

Jason Ekstrand (8):
  i965/nir: Make our environment variable checking smarter
  i965/fs: Make emit_lrp return an fs_inst
  i965/nir: Use emit_lrp for emitting flrp
  i965/nir: Emit MUL + ADD for MAD on GEN <= 5
  i965/nir: Properly set the predicate on the SEL used in min/max
  i965: Add a NIR analysis pass for determining when a boolean resolve
    is needed
  i965/nir: Do boolean resolves on GEN <= 5
  i965: Use NIR by default for Fragment shaders on SNB+

Matt Turner (1):
  i965/cmod_propagation: Ignore type in cmod prop if scan_inst is cmp
