[Mesa-dev] [PATCH 0/8] Clean up fixed function vertex shader key

[Mathias.Froehlich at gmx.net]

From: Mathias Fröhlich <Mathias.Froehlich at gmx.net>

Hi all,

The following series applies some optimizations to fixed
function vertex shader hash key generation. Most is targeted
to get a smaller hash key to get a smaller cache footprint and
a shorter final key to compare.
Two of the changes avoid possible different shader hash keys
if they do not result in a different final shader.

The series introduced no regressions in a piglit run on
i965 and radeonsi.

Please review

best

Mathias



Mathias Fröhlich (8):
  mesa: Get the point size array state from varying_vp_inputs.
  mesa: Move seperate_specular into the lighting section.
  mesa: Encode fog modes in a 2 bit field.
  mesa: texgen_enabled is only 1 bit.
  mesa: Remove unused bit in ffvertex_prog state_key.
  mesa: Remove unused ffvertex_prog texunit_really_enabled.
  mesa: Reduce ffvertex_prog state_key to 36 bytes.
  mesa: Care for differences in fog mode only if fog is consumed.
