[Mesa-dev] [PATCH 0/3] r600g patches

[Vadim Girlin]

#1 fixes slots order for x & y writes in the LIT implementation.
Without this patch "fp-lit-mask" piglit test fails after patch 3. It seems
wrong order causes wrong PV.* values for the next instruction.

#2 reduces unneeded calls to r600_spi_update.

#3 implements color clamping in shaders by adding "MOV_SAT R,R"
instructions for each color output before export. Shaders are rebuilt when
clamping state changes.

Fixes https://bugs.freedesktop.org/show_bug.cgi?id=38440

There are no regressions with r600.tests on evergreen with these patches.

  r600g: LIT: fix x&y slots order
  r600g: optimize spi update
  r600g: implement fragment and vertex color clamp
