[Mesa-dev] [PATCH v2 0/3] intel: propagate constants to first source of 2-src instructions

[Iago Toral Quiroga]

This v2 addresses comments to v1, specifically constant folding of SHR/SHL
instructions now only take up to 5-bits from the shift count parameter, just
like the hardware does.

Also, patch 2 has been fixed to avoid hitting assertions that would then be
fixed by patch 3. I sent the series up to patch 2 to Jenkins and verified that
it came back green.

Iago Toral Quiroga (3):
  intel/compiler: allow constant propagation for int quotient and
    reminder
  intel/compiler: allow constant propagation to first source of 2src
    instructions
  intel/compiler: implement more algebraic optimizations
