<br>
I've just pushed a branch called presub to my git repo:<br>
<a href="http://cgit.freedesktop.org/%7Etstellar/mesa/" target="_blank">http://cgit.freedesktop.org/~tstellar/mesa/</a> This branch contains support<br>
for presubtract operations in the r300 compiler. The only operation<br>
that is currently being used is (1 - src0), but I'll be adding the other<br>
ones later. This is only enabled for r500 cards at the moment.<br>
<br>
In order to support presubtract operations, I had to make some pretty<br>
significant modifications to the radeon_pair_* compiler passes, the<br>
peephole optimizer and also the dataflow helper functions. If anyone is<br>
interested, comments and some additional testing would be helpful.<br>
<br>
Thanks.<br>
<br>
-Tom<br>
