[Mesa-dev] [PATCH 00/17] gallium: add support for NIR as alternate IR

[Rob Clark]

From: Rob Clark <robclark at freedesktop.org>

Only a few minor review comment changes since last time, most of which
should have already been sent to list individually.  But resending the
whole patchset to try to collect r-b's (and so anyone can tell me if
I missed some r-b's).

Hopefully Jason could look at the lower-io patches, which I think he
was at least close to liking?

The remaining parts missing r-b are the lower-builtin-uniforms patch
(and sadly I suspect the intersection of folks who know NIR and folks
who understand that code might just be me, so maybe an a-b would be
ok?) and the last patch, which I guess doesn't need quite so much NIR
expertise to review?

Rob Clark (17):
  gallium: refactor pipe_shader_state to support multiple IR's
  gallium: add NIR as a possible IR
  nir: add lowering pass for y-transform
  nir: add lowering pass for glDrawPixels
  nir: add lowering pass for glBitmap
  nir: clamp-color-output support
  nir: passthrough-edgeflags support
  nir: lower-io-types pass
  nir: move callsite of lower_outputs_to_temporaries
  nir: rename lower_outputs_to_temporaries -> lower_io_to_temporaries
  nir/lower-io: split out some helper fxns
  nir/lower-io: add support for lowering inputs
  glsl: export accessor for builtin-uniform descriptors
  mesa/st: split the type_size calculation into it's own file
  mesa/st: add nir pass for lowering builtin uniforms
  mesa/st: move things around a bit in st_create_fp_variant()
  mesa/st: add support for NIR as possible driver IR
