| | | | | | | | | | | | While it does rely on NIR, it's not really part of the NIR core. At the moment, it still builds as part of libnir but that can be changed later if desired.

| | | | | | | | | | | | | | | | | | The algorithm used is different from both the naive suggestion from the GLSL spec and the one used in GLSL IR today.

Sometimes, these constants are 2 and 0.5, so we can remove a multiply altogether. Other times, it can create more immediate constants, which can actually hurt. Finding a good balance here is tricky. While much more could be done, this simple patch seems to have a lot of positive benefit while having a low downside. shader-db results on Broadwell: total instructions in shared programs: 8963768 -> 8961369 (-0.03%) instructions in affected programs: 438318 -> 435919 (-0.55%) helped: 1502 HURT: 245 total cycles in shared programs: 71527354 -> 71421516 (-0.15%) cycles in affected programs: 11541788 -> 11435950 (-0.92%) helped: 3445 HURT: 1224 Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Eduardo Lima Mitev <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]> Reviewed-by: Matt Turner <[email protected]>
