[Mesa-dev] [PATCH 0/6] nv50/ir: PostRaConstantFolding improvements

This series reworks the structure of the pass to make it easier to add
more optimisations to it.

Also implements folding for mad on gf100+ ISAs to reduce instruction count
by ~0.37%

I can only test it on a gk106 for now.

Karol Herbst (6):
  nv50/ir: add LIMM form of mad to gk110
  nv50/ir: add LIMM form of mad to gm107
  nv50/ir: replace post_ra_dead by Instruction::isDead
  nv50/ir: rework postraconstantfolding pass
  nv50/ra: always prefer def == src2 for mad/sad
  nv50/ir: implement mad post ra folding for nvc0+
