[Mesa-dev] [PATCH 0/3] nv50/ir: Some set+slct based optimization

[Karol Herbst]

Doesn't break on games I tested with and piglit was okay with that as well.

Plan to test this on my Kepler card later.

total changes in shader-db:

total instructions in shared programs : 5751418 -> 5726007 (-0.44%)
total gprs used in shared programs    : 664007 -> 663147 (-0.13%)
total shared used in shared programs  : 548832 -> 548832 (0.00%)
total local used in shared programs   : 20956 -> 20956 (0.00%)
total bytes used in shared programs   : 61439848 -> 61168408 (-0.44%)

Karol Herbst (3):
  nv50/ir: optimize slct(b, c, set(a, 0)) to slct(b, c, a)
  nv50/ir: clean up src2 in ConstantFolding
  nv50/ir: convert slct with boolean result to set
