[Mesa-dev] [PATCH v2 0/6] nv50/ir: PostRaConstantFolding improvements

[Karol Herbst]

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

Still have to run a full piglit on my gk106 with this, but g80, gk110 and gm107
should be tested as well, but I can't.

v2: swaped the last two commits

changes for shader-db:
total instructions in shared programs : 2818606 -> 2808429 (-0.36%)
total gprs used in shared programs    : 379273 -> 379236 (-0.01%)
total local used in shared programs   : 9505 -> 9505 (0.00%)
total bytes used in shared programs   : 25837192 -> 25743616 (-0.36%)

                local        gpr       inst      bytes 
    helped           0          26        4093        4093 
      hurt           0          20          61          61

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