Dear all,
v5: replace ADD+0.5/FLOOR by RNDNE as suggested by Ilia Mirkin.
post from v4 follows:
This is a 90% rewrite of the earlier series.
- I removed the changes to the texture state and handle everything in the
shader. Since this was needed for cube arrays anyway, and also taking Rolands
concern into account I thought it is best to do this for the other arrays as
well.
- I've identified to the root cause why sb was having problems with the
GATHER_O instruction, and reworked the code to make sure that the related
texture instructions are all emitted in one CF clause, This is also required
for the SET_GRADIENT instructions.
- I've also correct the array index for cube textures now.
I didn't see any changes with
piglit run gpu -t texture -t gather -t formats
thanks for reviewing,
Gert
