[Mesa-dev] [PATCH 0/5] i965: Fix gl_BaseVertex for non-indexed draws

[Antia Puentes]

This series is the alternative to the discarded patch 6 of the series:
https://patchwork.freedesktop.org/series/41307/

It fixes gl_BaseVertex in i965 by calculating it as:
is_indexed_draw(~0/0) & firstvertex.

I have run jenkins for the last patch of the series and
the intermediate patch 3. No regressions found.

Antia Puentes (5):
  compiler: Add SYSTEM_VALUE_IS_INDEXED_DRAW and instrinsics
  intel/compiler: Add uses_is_indexed_draw flag
  intel: emit is_indexed_draw in the same VE than gl_DrawID
  compiler/nir: Add conditional lowering for gl_BaseVertex
  intel: activate the gl_BaseVertex lowering
